1SCA022830R4570 ABB 800 A 4-Pole IP65 Steel Enclosed Switch Disconnector

Why Choose the ABB OT800KLUU4BZ 800 A Enclosed Switch Disconnector?

The ABB OT800KLUU4BZ, order number 1SCA022830R4570, is a heavy-duty 800 A, 4-pole steel enclosed switch disconnector designed for dependable load breaking and electrical isolation in demanding industrial installations. Part of ABB’s OT enclosed switch-disconnector range, it combines high-current switching performance with a robust IP65 galvanised steel enclosure.

Designed for substantial electrical loads requiring four-pole isolation, the OT800KLUU4BZ provides simultaneous switching of four conductors. It has a rated operational current of 720 A AC-23A at 380–415 V, 500 V and 690 V, with motor switching capability of 400 kW at 415 V AC and 710 kW at 690 V AC.

The enclosure is supplied with blank cable entries at the top and bottom and is prepared for industrial cable termination arrangements. A black pistol-type I-O / ON-OFF handle, N and PE terminals, cover interlocking and defeatable interlocking are incorporated into the assembly, providing a practical high-current isolation solution for machinery, distribution systems and industrial power applications.

Reliable Four-Pole High-Current Isolation

The ABB OT800KLUU4BZ combines a high-capacity four-pole switch-disconnector, operating mechanism and protective IP65 enclosure into a complete assembly for local electrical isolation. Its four-pole configuration enables four conductors to be switched together, making it suitable for industrial systems where complete four-pole isolation is required.

The galvanised steel enclosure incorporates a polyester coating, gas-pressure relief function and an earthed door, while the operating handle can be secured with up to three padlocks. Blank top and bottom cable entries allow the termination arrangement to be adapted to the installation, with the enclosure prepared for both single and parallel cable configurations.

Typical Applications

• High-current four-pole electrical isolation.
• Three-phase distribution systems requiring four-pole switching.
• Industrial mains and sub-main isolation.
• Large industrial motors and machinery.
• Manufacturing and production facilities.
• Large pumps, fans and ventilation systems.
• Compressors and heavy processing equipment.
• Industrial power distribution equipment.
• Local maintenance and safety isolation points.
