1SCA022342R7460 ABB 800 A 4-Pole IP65 Steel Enclosed Switch Disconnector

Why Choose the ABB OT800KLAA4BZ 800 A Steel Enclosed Switch Disconnector?

The ABB OT800KLAA4BZ, order number 1SCA022342R7460, is a heavy-duty 800 A, 4-pole steel enclosed switch disconnector designed for dependable load breaking and electrical isolation in high-current industrial installations. Part of ABB’s OT enclosed switch-disconnector range, it combines robust switching performance with a durable IP65 steel sheet enclosure.

Designed for substantial three-phase systems requiring four-pole switching, the OT800KLAA4BZ enables four conductors to be switched and isolated together. The enclosure is supplied with open top and bottom cable-entry sides, allowing suitable C-flange or ring-flange cable-entry components to be selected separately according to the cable sizes and installation requirements.

The OT800KLAA4BZ has an authoritative equipment rating of 800 A and a 4-pole configuration. Its operational ratings include 720 A AC-22A at 690 V and 720 A AC-23A at 415 V. The 1000 × 400 × 230 mm steel enclosure provides practical space for high-current cabling while maintaining IP65 environmental protection.
