OTM63F3CMA24D ABB 63 A 3-Pole Motorised Changeover Switch 24 V DC

Why Choose the ABB OTM63F3CMA24D Motorised Changeover Switch?

The ABB OTM63F3CMA24D is a compact motorised changeover switch designed for reliable transfer between alternative electrical power sources in low-voltage distribution systems. Part of the ABB OT motorised changeover switch range, it combines a 63 A current rating with three-pole switching and a 24 V DC motor operator.

This switch provides motorised source changeover for applications where electrical loads need to be transferred between two supplies. Its integrated motor operator enables remote electrical switching, while a manual operating handle provides local control when required.

With a rated current of 63 A, a 3-pole configuration, a 24 V DC motor operating voltage and a 30 kW rating, the OTM63F3CMA24D is suited to mains and standby systems, generator changeover installations and three-phase industrial or commercial distribution assemblies.
