Why Choose the ABB OT1600E04CP Manual Change-Over Switch?
The ABB OT1600E04CP is a heavy-duty 1600 A four-pole manual change-over switch designed for controlled switching between two electrical power sources. Identified by ABB order code 1SCA149829R1001, it belongs to ABB's OT change-over switch range and provides dependable manual source selection for high-current power-distribution systems.
The OT1600E04CP uses I-O-II open-transition operation, providing a defined OFF position between the two connected-source positions. Its four-pole configuration enables simultaneous switching of four conductors, while its base-mounted construction and 1000 V AC operational-voltage capability make it suitable for substantial industrial and commercial electrical installations.
Engineered for demanding switching duties, the OT1600E04CP has a 1600 A thermal and AC-22A rating and an AC-23A operational current rating of 1250 A at up to 415 V. A rated short-time withstand current of 50 kA rms for 1 second provides robust short-circuit withstand performance for appropriately designed switchboard systems.

Heavy-Duty Four-Pole Manual Source Change-Over
The ABB OT1600E04CP provides manual selection between two electrical sources through an I-O-II open-transition operating sequence. The OFF position separates the two connected-source positions so that the active source is disconnected before the alternative source is connected, providing controlled source transfer without intentional source overlap.
With its 1600 A four-pole construction, 1000 V AC operational-voltage capability and 50 kA short-time withstand rating, the OT1600E04CP is engineered for high-current change-over duties in industrial and commercial distribution systems. Its four switched poles make it particularly suitable where the installation requires four conductors to be transferred as part of the source change-over arrangement.
Typical Applications
- Manual mains and generator change-over systems.
- High-current four-pole source-selection systems.
- Industrial power-distribution switchboards.
- Standby and alternative power installations.
- Commercial building electrical distribution.
- Infrastructure and critical-power systems.
- Manufacturing and process-industry facilities.
- OEM change-over and power-control panels.
