OTM200E4WCM230C ABB 200 A 4-Pole 230 V AC Motorised Change-Over Switch

Why Choose the ABB OTM200E4WCM230C Motorised Change-Over Switch?

The ABB OTM200E4WCM230C is a robust 200 A four-pole motorised change-over switch designed for controlled switching between two electrical power sources. As part of the ABB OT Change-over Switches product group, it combines ABB's proven OT switching technology with an integrated motor operator for industrial, commercial and standby power distribution applications.

The OTM200E4WCM230C provides I-O-II open-transition operation, creating a defined OFF position between the two source positions so that one supply is disconnected before the alternative supply is connected. Its integrated motor operator uses a 220–240 V AC supply, while the supplied handle enables manual operation when required for commissioning, maintenance or local intervention.

With a rated operational current of 200 A, a four-pole configuration and an AC-23 operational power rating of 110 kW at 400 V, the OTM200E4WCM230C is suited to demanding power transfer applications. The W version features extended phase distance, providing additional spacing between phases for compatible switchboard installations.

Reliable 230 V AC Motorised Power Source Change-Over

Motorised change-over switches such as the ABB OTM200E4WCM230C enable electrical power sources to be selected remotely without requiring routine manual switching at the electrical panel. The integrated motor mechanism operates the switch while its I-O-II open-transition arrangement maintains a defined electrical break between the two sources during transfer.

The OTM200E4WCM230C combines a 200 A rating with four-pole switching, a 220–240 V AC motor operator and extended phase distance. ABB supplies the switch with a handle for manual operation, a bolt kit with nuts and washers for the terminals and male connectors for the control circuits, providing a practical solution for switchboard installation and maintenance.

Typical Applications

• Motorised mains-to-generator change-over systems.
• Standby and alternative power supply switching.
• Industrial electrical distribution systems.
• Commercial building power distribution.
• Switchboards and electrical distribution panels.
• Remote 230 V AC controlled source-selection systems.
