OTM315E3CM110V ABB 315 A 3-Pole Motorised Open-Transition Change-Over Switch

Why Choose the ABB OTM315E3CM110V Motorised Change-Over Switch?

The ABB OTM315E3CM110V is a 315 A three-pole motorised change-over switch designed for controlled switching between two electrical power sources. Part of the ABB OT Change-over Switches range, it combines ABB's OT switching platform with an integrated motor operator for industrial, commercial and standby power distribution applications.

The OTM315E3CM110V 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 motorised mechanism enables remote source selection, while the direct-mounted operating arrangement also supports manual operation when required.

Rated at 315 A with a three-pole configuration, the OTM315E3CM110V provides a rated apparent power of 215 kVA at 400 V and AC-31B / AC-33B ratings of 315 A at 415 V. Its open-transition design and motorised operation make it suitable for mains, generator and alternative-source switching in substantial low-voltage distribution systems.

Reliable Motorised Open-Transition Power Source Change-Over

Motorised change-over switches such as the ABB OTM315E3CM110V enable electrical power sources to be selected remotely without requiring routine manual switching at the electrical panel. The motorised mechanism actuates the switch while its I-O-II open-transition arrangement provides a defined electrical break between the two source positions during transfer.

The OTM315E3CM110V combines a substantial 315 A rating with three-pole switching and direct-mounted operation. Its 215 kVA apparent power rating at 400 V and 315 A AC-31B / AC-33B ratings at 415 V make it a practical choice for motorised source-selection duties in suitably engineered low-voltage switchboards.

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 main distribution panels.
• Remote source-selection and power transfer systems.
