OTM3200E4CM230C ABB 3200 A 4-Pole 230 V AC Motorised Change-Over Switch

Why Choose the ABB OTM3200E4CM230C Motorised Change-Over Switch?

The ABB OTM3200E4CM230C is a heavy-duty 3200 A four-pole motorised change-over switch designed for controlled switching between two high-current electrical power sources. Part of the ABB OT Change-over Switches range, it combines high-capacity switching with an integrated motor operator for industrial, commercial, infrastructure and standby power distribution systems.

The OTM3200E4CM230C provides I-O-II open-transition operation, giving a defined OFF position between the two source positions so that one supply is disconnected before the alternative supply is connected. Its integrated 220–240 V AC motor operator enables remote electrical switching, while the direct-mounted handle provides local manual operation when required.

Rated at 3200 A with a four-pole configuration, the OTM3200E4CM230C is engineered for substantial low-voltage power transfer duties. The fourth pole is positioned on the right and operates simultaneously with the main poles, while the switch supports either top-in/bottom-out or bottom-in/top-out terminal arrangements for installation flexibility.

Reliable 3200 A Motorised Power Source Change-Over

Motorised change-over switches such as the ABB OTM3200E4CM230C enable high-capacity electrical power sources to be selected remotely without requiring routine manual switching at the main switchboard. The integrated 220–240 V AC motor drive actuates the switch while its I-O-II open-transition arrangement provides a defined electrical break between the two source positions during transfer.

The OTM3200E4CM230C combines a substantial 3200 A rating with four-pole simultaneous switching, direct-mounted manual operation and flexible terminal orientation. Its base-mounted, front-operated construction is designed for integration into suitably engineered high-current switchboards and power distribution assemblies.

Typical Applications

• High-current mains-to-generator change-over systems.
• Large standby and alternative power supply systems.
• Industrial main electrical distribution systems.
• Commercial and infrastructure power distribution.
• Large switchboards and main low-voltage distribution panels.
• Remote motorised source-selection and power transfer systems.
