Manual transfer switch
What is a manual transfer switch?
A manual transfer switch is a device that allows you to manually switch between different power sources. It is generally used in situations where it is necessary to switch quickly and safely between a main power source and an emergency power source.
Socomec's range of manual transfer switches
Our range of Socomec manual changeover switches offers a variety of solutions to meet different needs.
COMO CS: Manual cam rotary switches from 25 to 100 A
COMO CS are manually operated multi-pole switches for switching, reversing sources or permuting two low-voltage power circuits on load, as well as their safety isolation. Available from 25A to 100A, they are quick to assemble thanks to the "quick fix" device and easy to install with common accessories. They are effective in all circumstances, available with 3 standard switching types. Compliant with IEC 60947-3 and UL 60947-4-1 standards, they are suitable for use in industry, particularly for machine control.
COMO CS switchgear solutions in enclosures
Available for switching types I-II and I-0-II, with different enclosure sizes to suit requirements. For maximum safety during maintenance operations, the handle is triple-locked in position 0 (position I for switching type I-II). They have IP65/NEMA4.4X protection against dust and water jets, with a red-yellow handle for the control unit.
SIRCO M: Manual changeover switches from 25 to 125 A
SIRCO M switches are modular, 3 or 4-pole, manually-operated changeover switches with fully visible disconnection. They provide on-load switching of two low-voltage power circuits, as well as their safety isolation. Equipped with step contacts and a double break per phase, they provide safe disconnection. Modular, they can be mounted on rails, plates or modular panels, enabling on-load switching thanks to their AC23 characteristic. They comply with IEC 60947-3. This solution is particularly suitable for healthcare buildings and the manufacturing industry, offering safe disconnection, modularity and on-load switching.
SIRCOVER : Manual source changers from 125 to 3200 A
SIRCOVER products are manually operated changeover switches offering different ranges to suit various applications, such as open transition switching, contact overlap and bypass. With stable positions and safe on-load switching, they are available in I-0-II, I-I+II-II, bypass, and bypass with contact overlap versions. SIRCOVERs offer a comprehensive range, ease of connection and can be used in direct front-end mode or with external handles. This solution is particularly suitable for power manufacturing and distribution. They comply with IEC 60947-6,-1, IEC 60947-3, GB/T 14048-11.
SIRCOVER ATS Bypass : Manual changeover switches from 125 to 1600 A
SIRCOVER ATS Bypass manual changeover switches, with a capacity of 125 to 1600 A, are manually operated four-pole switches with fully apparent breaking. Designed to isolate ATS (automatic transfer switch) or ASI (UPS) type electrical equipment while maintaining power to the load, these Socomec switches enable the source used to power the load to be selected in the Bypass position.
The advantages of the SIRCOVER ATS Bypass include three stable positions unaffected by voltage drops and vibrations, on-load switching thanks to their AC-22 characteristics in compliance with the IEC 60947-3 standard, and safe disconnection with simultaneous upstream and downstream isolation. This is a complete solution offering both an equipment isolation function and a switching function.
This solution is ideal for industry and healthcare buildings, with strengths such as stable positions, on-load switching, safe disconnection and a complete solution. The SIRCOVER ATS Bypass complies with IEC 60947-3, guaranteeing performance in line with international standards.
Manual changeover switch for generator set
Socomec's range of manual source inverters are used in electrical installations to manually switch the power supply of an equipment or system between the main source of the electrical network and an emergency generator.
This type of source inverter is particularly important in environments where a continuous power supply is crucial, such as critical installations, data centres, hospitals, or any other location where a power failure could have serious consequences. In the event of a power failure from the main source, the manual source inverter enables rapid switching to the genset to ensure a continuous supply.
