Why Choose the ABB OT1600E12CP Manual Change-Over Switch?
The ABB OT1600E12CP is a heavy-duty 1600 A three-pole manual change-over switch designed for controlled switching between two electrical power sources. Identified by ABB order code 1SCA103293R1001, it belongs to the ABB OT1600_C range and provides dependable manual source selection for high-current industrial and commercial power-distribution systems.
The OT1600E12CP provides I-O-II open-transition operation, with a defined OFF position between the two source positions. Its three-pole configuration is designed for three-phase applications, while the operating mechanism is positioned between the poles for a compact and practical switchboard arrangement.
Engineered for demanding electrical duties, the OT1600E12CP has a rated operational voltage of 1000 V, a conventional free-air thermal current of 1600 A and a rated short-time withstand current of 50 kA rms for 1 second. It is supplied with a black plastic IP65 I-O-II pistol-type handle, operating shaft and bolt set for cable connection.

Heavy-Duty Three-Pole Manual Source Change-Over
The ABB OT1600E12CP provides controlled manual source selection through an I-O-II open-transition sequence. The defined OFF position separates the two connected-source positions so that the active source is disconnected before the alternative source is connected, making the switch suitable for mains, generator and other alternative-source arrangements.
Its 1600 A three-pole construction, mechanism-between-poles configuration and 50 kA for 1 s short-time withstand capability make the OT1600E12CP suitable for substantial three-phase distribution systems. The supplied IP65 pistol handle, shaft and cable-connection hardware provide a coordinated ABB solution for professional switchboard integration.
Typical Applications
- Manual mains and generator change-over systems.
- Three-phase power-source selection.
- High-current industrial switchboards.
- Standby and alternative power systems.
- Commercial building power distribution.
- Infrastructure and critical-power installations.
- Manufacturing and process-industry facilities.
- OEM change-over and power-control panels.
