£683.65
The ABB OT500E04P is a heavy-duty 500 A four-pole switch-disconnector engineered for safe switching and dependable electrical isolation in industrial power distribution systems. As part of ABB's proven OT switch-disconnector range, it combines robust construction with high electrical performance, making it ideal for demanding commercial and industrial installations.
Supplied complete with a black IP65 external operating handle, adjustable operating shaft and terminal bolt kit, the OT500E04P is designed for quick installation within switchboards and electrical control panels. The fourth pole switches simultaneously with the main poles, making it suitable for applications requiring neutral isolation.
With a rated operational current of 500 A, a four-pole configuration and suitability for systems up to 1000 V AC, the OT500E04P provides reliable manual isolation for industrial electrical circuits while delivering a long mechanical service life and excellent short-circuit withstand capability.
The ABB OT500E04P provides a safe and dependable method of manually isolating high-current three-phase circuits with switched neutral. Its four-pole design is particularly suitable where complete circuit isolation is required during maintenance, servicing or emergency shutdown procedures.
The supplied external IP65 operating handle enables switching from outside the enclosure while maintaining environmental protection. The handle can be padlocked in the OFF position to support lockout/tagout procedures and improve operator safety during maintenance work.
