CHANGE-OVER SWITCH OTM125F4CMA230V

Motor-operated transfer switches
ABB offers a wide range of open motor-operated transfer switches in the range of 40–3200 A. All visually refreshed motor-operated transfer switches now feature a new enclosure with clear operating instructions and improved motor control.

Shorter installation time
Installing ABB motor-operated transfer switches is fast and easy. Voltage-sensing connectors save time, as no holes need to be drilled into the busbars. Control wiring is also secured with screws, ensuring a safe and reliable connection even during transport.
   
Safe and reliable
The switches feature a comprehensive range of internal protection features, such as mechanical interlocking, which ensures isolation between two asynchronous power sources. This prevents the risk of short-circuiting between them. Motor-operated transfer switches also include a handle for manual operation in emergency situations.

Excellent performance
Ensuring excellent performance is extremely important to us. For switching applications where the loaded switch may need to be operated remotely, sufficient durability has been verified by testing against the IEC 60947-6-1 standard for durability requirements.

Space-saving design
ABB provides compact and cost-effective components for all installations. ABB motor-operated transfer switches are on average 20% smaller than comparable products on the market. This product description is an automated translation of the original Finnish description.
