OT2000E03CP ABB 2000 A 3-Pole Manual Change-Over Switch

Why Choose the ABB OT2000E03CP Manual Change-Over Switch?

The ABB OT2000E03CP is a heavy-duty 2000 A three-pole manual change-over switch designed for controlled switching between two electrical power sources. Identified by ABB order code 1SCA103908R1001, 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 OT2000E03CP provides I-O-II open-transition operation, giving the operator 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 at the end of the switch for integration into high-current switchboard assemblies.

Engineered for demanding installations, the OT2000E03CP has a conventional free-air thermal current of 2000 A, a rated operational voltage and insulation voltage of 1000 V, and high short-time withstand capability. The switch includes a black plastic IP65 I-O-II pistol-type handle, operating shaft and bolt set for cable connection.

Heavy-Duty 2000 A Manual Source Change-Over

The ABB OT2000E03CP provides controlled manual selection between two electrical sources through an I-O-II open-transition sequence. The defined OFF position ensures that the selected source is disconnected before the alternative source is connected, making the switch suitable for mains, generator and other alternative-source arrangements where simultaneous connection is not required.

Its 2000 A three-pole construction, 1000 V capability and high short-time withstand performance make the OT2000E03CP 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 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.
