IEC Motor Control

IEC Motor Control

Sirius Innovations

Switching of fixed speed motors is realized by switching devices such as SIRIUS contactors, direct and reversing starters or soft starters. Besides their favorable cost-performance ratio, these devices are particularly characterized by their low power loss. This results in lower energy consumption as well as minimized cooling expenditures in the service room or control cabinet. Soft Starters or star-delta starters allow for soft motor start-up, which reduces electric and mechanical peak loads by up to 60%, thereby reducing the load on the motor and the energy consumed during start up.

The rugged construction, heavy-duty ratings and a wide selection of control options and accessories makes the Siemens lighting and heating contactors the right choice for your applications.

Manual Starters & Switches

A manual starter is a motor controller whose contact mechanism is operated by a mechanical linkage from a toggle handle or push button which is in turn operated by hand. A thermal unit and direct acting overload mechanism provides motor running overload protection. Basically, a manual starter is an “ON-OFF” switch with overload protection. Siemens manual starters and switches are used in many applications for local control of equipment in the industrial or construction markets, such as operating power saws, pumps, fans, conveyors, blowers, packaging, sorting and other machinery. These starters are UL listed and CSA approved. Siemens offers a variety of manual starters for various applications. This is a test.

NEMA Overload Relays

From general applications to special applications, Siemens offers a wide range of overload relays that provide superior motor protection. Overload relays are used to protect motors from excessive heat resulting from sustained motor overloads, rapid motor cycling, stalled rotor conditions and phase loss.

Pump Control Panels

Pump controllers monitor flow and/or level variables and control a pump accordingly to maintain the desired levels. Pump control can include simply turning a pump on and off or more advanced controls for pump speed, output pressure, etc. Installation is easy. The pump control panel is factory wired to provide flexible control and protect against short circuits and overloads. Ample space is provided for field modifications and installation of accessories. Siemens offers the NEMA Slim Line Class 82, Full Voltage Type Class 87, Reduced-Voltage Type Class 88 and Vacuum Starter Type Class 87.

Reduced Voltage Starters

When a motor is energized by a full voltage starter, mechanical and electrical problems can occur. Potential mechanical problems include broken belts, gears or couplings or spilt or broken product. Potential electrical problems include deterioration of motor insulation or brown outs causing nuisance problems with other electrical equipment.

A reduced voltage starter helps to lessen these problems by reducing inrush line current and/or starting torque of a motor applied to the drive load. This is done by either reducing voltage applied to the motor during starting or by using only part of the motor windings during starting.

Siemens manufactures three commonly used electromechanical reduced voltage starters. Each one is designed for specific application requirements and consists of auto transformer, wye-delta and part-winding starters.

Solid State Control

Solid State Control

Hybrid Starters (3RM1)

Does every inch count in your control cabinet? The solution: Motor switching and protection in a width of only 22.5 mm. Depending on its function, the motor starter footprint will save up to 86% compared to conventional motor starters.

You will no longer need redundant contactors when using the safety versions, another space savings. They are available in direct or reversing and are suitable for switching small motors up to 3 HP.

Soft Starters

Nowadays, three-phase motors represent the most favored type of drive concept. Direct starting or star-delta starting is, in many cases, not the best solution. Such methods often result in unpleasant side-effects such as mechanical impacts inside the machine or voltage dips in the power supply system.

Our new SIRIUS family of soft starters is a comprehensive range of products covering all the standard and high-feature motor-starting applications. The advantages of soft start-up and smooth ramp-down with these devices can therefore be exploited in the most varied of applications for simple and economically efficient machinery and equipment layouts.

Circuit Breakers

Circuit Breakers Overview

Siemens circuit breakers protect your electrical apparatus helping to minimize down-time at lower costs. We develop a wide range of circuit breakers with ampacities up to 5000A that are equipped with numerous communication capabilities, have various modular designs and are certified with global ratings.

IEC Miniature Circuit Breakers

IEC style miniature circuit breakers (MCB) according to ENNEC 60 898 are not always permitted in North America. For this reason, MCBs were developed that were based on the miniature circuit breakers of the 5SY series and met the special requirements of UL 489.

Within the sphere of influence of NEMA (National Electrical Manufacturers Association) and ANSI (American National Standards Institute) MCBs are certified as a solution for protective applications and can be used for branch circuit protection in the branches of control panels and systems.

The connection terminals are designed for the class: "Field wiring". This means that, as well as being installed in a factory, the MCBs can be installed locally at customer sites. In addition to the permissible tripping ranges according to UL 489, device tipping characteristics C and D to ENNEC 60 898 have also been adapted. Therefore, the MCBs comply with both standards.

Molded Case Circuit Breakers

Control Circuit Protection

Control Circuit Protection

Control Circuit Protection Overview

Siemens circuit protection devices are engineered to allow for easy deployment, quick installation and secure protection of industrial devices from excessive current flow. Siemens low voltage circuit protection devices such as, miniature circuit breakers, supplementary protectors and fuse holders, range in performance and style to meet wide-ranging needs.

Supplementary Protectors

Siemens' UL 1077 Supplementary Protectors are designed to provide additional protection along with a branch circuit protection device. Since our Supplementary protectors are made to trip faster than a standard UL 489 Circuit Breaker they are able to provide additional protection for more sensitive devices inside the panel. Supplementary protectors can used in a number of industrial applications such as to provide selectivity for multiple motor control circuits on the secondary side of a control transformer or power supply by allowing the user to quickly find the problem circuit should a fault occur without having to shut down all of the other control circuits. Supplementary protectors may also be used as a local disconnecting means inside the panel when a branch circuit protection device is already present.

Fuses & Fuse Holders

All fuse holders are equipped with either a fuse handle or draw mechanism for easy insertion and removal of cylindrical type fuses. During insertion and removal the fuses are isolated from the power/control circuit. Their compact size requires less space than typical open-type fuse holders and they mount directly onto standard 35 mm mounting rails. Fuse holders for 8mm x 32 mm, 10 mm x 38 mm fuses in the 1 + N draw design occupy the same mounting space as 1 pole designs. This unique design saves space when compared to the typical handle type fuse holder which requires two poles.

Terminal Blocks

For the wiring of machines and system controls Siemens terminal blocks with Screw, Spring Loaded and Insulation Displacement Connections meet or exceed the requirements of CSA, IEC, NEMA, UL, VDE and other international Standards. Meeting these requirements, combined with worldwide acceptability and availability, enables Siemens terminal blocks to be used domestically; and, incorporated into equipment which will be exported. Virtually all terminal block bodies are insulated on both sides eliminating the need for barriers and end plates. The materials used are ecologically harmless; e.g. cadmium-free, and without halogens or silicone. The terminals are finger-touch safe and cannot be installed onto a mounting rail due to their symmetrical design. In response to these trends Siemens has expanded existing and added new terminal block lines.
