OT630E33CP ABB 630 A 6-Pole Manual Change-Over Switch

Why Choose the ABB OT630E33CP Change-Over Switch?

The ABB OT630E33CP is a heavy-duty 630 A manual change-over switch designed for reliable source selection in industrial and commercial power distribution systems. As part of the ABB OT Change-over Switches product group, it provides dependable manual switching between two electrical supplies with an open-transition operating sequence.

Designed for demanding power distribution applications, the OT630E33CP uses I-O-II operation with a stable OFF position. This open-transition arrangement disconnects one source before the alternative source is connected, making the switch suitable for mains, generator, standby supply and other applications requiring controlled manual transfer between two power sources.

With a rated operational current of 630 A and a six-pole configuration, the OT630E33CP is suited to high-current installations requiring multiple conductors to be switched simultaneously. The switch is supplied with a black plastic IP65 pistol handle, shaft and bolt set for cable connection, supporting straightforward integration into suitable switchboards and electrical enclosures.
