Why Choose the ABB OTM160E4CM110V Motorised Change-Over Switch?
The ABB OTM160E4CM110V is a 160 A 4-pole motorised change-over switch designed for controlled transfer between two electrical power sources in low-voltage distribution systems. Part of the ABB OT change-over switch range, it combines an integrated motor operator with robust four-pole switching for industrial, commercial and infrastructure applications.
The OTM160E4CM110V provides I-O-II open-transition operation, disconnecting one source before the alternative source is connected. Its motor operator is designed for a 110–125 V AC/DC operating supply, enabling electrically controlled source transfer while retaining manual operation through the supplied handle.
Rated at 160 A with a 4-pole configuration, the OTM160E4CM110V delivers 160 A AC-23A switching capability at 380–415 V and 90 kW AC-23A operational power at 400–415 V. The fourth pole is positioned on the right and switches simultaneously with the other poles, providing coordinated four-pole source transfer.
