Why Choose the ABB OTM800E4CM230C Motorised Changeover Switch?
The ABB OTM800E4CM230C is a heavy-duty 800 A 4-pole motorised changeover switch designed for reliable switching between two electrical power sources in industrial and commercial power distribution systems. As part of the ABB OT motorised changeover switch range, it combines high-current switching performance with an integrated motor operator for convenient remote control.
This motorised changeover switch provides I-O-II operation, allowing controlled open-transition transfer between two power sources with a defined OFF position. It is particularly suitable for mains-to-generator changeover, alternative supply selection and power distribution installations where dependable source switching is essential.
With a rated current of 800 A, a 4-pole configuration and a 220–240 V AC motor operating voltage, the OTM800E4CM230C is engineered for demanding three-phase power systems where the neutral conductor also needs to be switched. The unit includes a handle for manual operation, terminal bolt hardware and connectors for the control circuits.
