The ABB OT1250E13CP is a heavy-duty 4-pole 1250 A manual change-over switch designed for dependable manual transfer between two electrical power sources. As part of the ABB OT Change-over Switches range, it provides I-O-II operation with a stable OFF position for industrial power distribution, switchboards and high-current supply change-over applications.
Designed for open-transition switching, the OT1250E13CP disconnects one power source before connecting the alternative source. The operating mechanism is positioned between the poles, providing a practical configuration for switchboard installations. The switch includes a black plastic IP65 I-O-II pistol handle, operating shaft and bolt set for cable connection, with the handle padlockable in the O position.
With a rated operational current of 1250 A and a 4-pole configuration, the OT1250E13CP is engineered for demanding low-voltage distribution systems where four conductors require change-over switching. It provides an AC-23A operational current of 1250 A at 380–415 V and an operational power rating of 560 kW at 400–415 V.
Manual change-over switches provide a controlled method of transferring an electrical load between two power sources. The ABB OT1250E13CP uses open-transition I-O-II operation, ensuring the connected source is disconnected before the alternative source is connected while providing a stable OFF position between the two operating states.
The four-pole configuration allows four conductors to be switched together, while the mechanism-between-poles arrangement provides a practical layout for demanding switchboard designs. With its 1250 A rating, high short-time withstand capability and secure manual operating features, the OT1250E13CP is suitable for main distribution boards, generator change-over systems and industrial power installations.
