OT2000E04CP ABB 2000 A 4-Pole Manual Change-Over Switch

Why Choose the ABB OT2000E04CP Manual Change-Over Switch?

The ABB OT2000E04CP is a heavy-duty 2000 A four-pole manual change-over switch designed for controlled switching between two electrical power sources. Identified by ABB order code 1SCA103912R1001, it belongs to the ABB OT2000_C range and provides robust manual source selection for high-current industrial, commercial and infrastructure power-distribution systems.

The OT2000E04CP provides I-O-II open-transition operation, giving the operator a defined OFF position between the two source positions. Its four-pole configuration enables four conductors to be switched as part of the source-transfer operation, while the operating mechanism is positioned at the left end of the switch.

Engineered for demanding installations, the OT2000E04CP has a conventional free-air thermal current of 2000 A, a rated operational voltage of 1000 V 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 Four-Pole Manual Source Change-Over

The ABB OT2000E04CP provides controlled manual selection between two electrical sources through an I-O-II open-transition sequence. The defined OFF position ensures that one source is disconnected before the alternative source is connected, making the switch suitable for mains, generator and other alternative-source arrangements where intentional source overlap is not required.

Its 2000 A four-pole construction, 1000 V capability and 50 kA for 1 s short-time withstand rating make the OT2000E04CP suitable for substantial power-distribution systems. The included IP65 pistol handle, operating shaft and cable-connection hardware provide a coordinated ABB solution for professional switchboard integration.

Typical Applications

• Manual mains and generator change-over systems.
• Four-pole high-current source selection.
• Industrial main distribution switchboards.
• Standby and alternative power systems.
• Large commercial building power distribution.
• Infrastructure and critical-power installations.
• Manufacturing and process-industry facilities.
• OEM high-current change-over and power-control panels.
