1SCA022562R9910 ABB Steel Enclosed Switch-Disconnector 125 A 4 Pole

Why Choose the ABB OTL125B4U Enclosed Switch-Disconnector?

The ABB OTL125B4U is a robust 125 A steel enclosed switch-disconnector designed to provide dependable local isolation of industrial machinery, motors and electrical distribution circuits. With ABB product ID 1SCA022562R9910, this four-pole unit combines reliable load-breaking performance with a rigid alu-zinc coated steel enclosure for demanding industrial installations.

As part of the ABB OTL enclosed switch-disconnector series, the OTL125B4U features an IP65 steel sheet enclosure with polyester powder coating, a black pistol-type operating handle and an interlocked hinged door. The cover interlock prevents normal opening while the switch is ON, while the defeatable interlock allows authorised access when required for procedures such as thermographic inspection.

With a rated operational current of 125 A at 380–415 V AC-22A and 90 A at 380–415 V AC-23A, the OTL125B4U is suitable for substantial industrial loads and motor isolation duties. Its four-pole configuration, 45 kW motor switching capability at 415 V and blank top and bottom cable entries provide a flexible solution for industrial power isolation.
