Why Choose the ABB OT400E04P Switch-Disconnector?

The ABB OT400E04P is a heavy-duty 400 A four-pole switch-disconnector engineered for safe isolation and manual switching in industrial power distribution, machinery and commercial electrical installations. As part of the proven ABB OT switch-disconnector range, it delivers dependable performance, high switching capacity and long service life in demanding low-voltage applications.

This front-operated switch-disconnector is supplied complete with a black IP65 operating handle, operating shaft and terminal bolt kit, simplifying installation into electrical switchboards and control panels. The lockable handle enhances operational safety by allowing the switch to be secured in the OFF position during maintenance and servicing.

With a rated operational current of 400 A, a four-pole switching configuration and a rated operational voltage of up to 1000 V AC, the OT400E04P is ideally suited for isolating high-current three-phase systems where neutral switching is also required. Its robust base-mounted design ensures reliable operation across a wide range of industrial environments.
