Why Choose the ABB OT200E04WCP 200A 4-Pole Change-Over Switch?
The ABB OT200E04WCP is a robust and reliable 200 A four-pole manual change-over switch designed for safe and efficient switching between two electrical power supplies in industrial, commercial and electrical distribution applications. As part of the ABB OT change-over switch series, it provides dependable manual source selection and load isolation for switchboards, distribution panels and industrial control systems.
This switch features a three-position I-0-II operating mechanism, allowing operators to select between two power sources or disconnect the load in the central OFF position. Its open-transition switching mechanism ensures that the first supply is disconnected before the alternative supply is connected, preventing unintended paralleling of the two sources during manual changeover.
With a rated operational current of 200 A, a four-pole switching configuration and a rated operational voltage of up to 1000 V, the OT200E04WCP is suitable for demanding low-voltage power distribution installations. Its wide phase-distance construction, included operating handle and shaft, and robust base-mounted design make it a practical solution for manual mains-to-generator changeover and other dual-supply applications.

Reliable Manual Power Source Changeover
Manual change-over switches such as the ABB OT200E04WCP enable operators to transfer electrical loads between two separate power supplies. The three-position I-0-II mechanism provides a defined operating sequence, allowing the load to be connected to source I, completely disconnected in position 0, or connected to source II.
The open-transition switching mechanism disconnects the active source before connecting the alternative supply. This makes the switch suitable for appropriately designed mains-to-generator changeover systems, alternative feeder selection and industrial power distribution arrangements where simultaneous connection of two independent sources must be avoided.
The four-pole configuration enables simultaneous switching of four conductors, including a neutral conductor where required by the electrical installation design. The wide phase-distance construction provides additional space around the power terminals, while the included operating shaft and padlockable handle support installation within industrial switchboards and electrical control cabinets. The switch is manually operated and does not provide automatic transfer functionality or overcurrent protection; suitable protective devices and system interlocks must be provided as required by the installation.
Typical Applications
- Manual mains-to-generator changeover systems.
- Industrial and commercial electrical distribution boards.
- Dual power supply selection and transfer systems.
- Generator connection and standby power installations.
- Industrial switchboards and low-voltage switchgear assemblies.
- Manufacturing plants and production facilities.
- Commercial buildings and infrastructure power distribution.
- Electrical maintenance and supply isolation applications.
- Industrial machinery and process control power systems.
- OEM electrical panel building and power distribution equipment.
