Why Choose the ABB OTL125B3U Enclosed Safety Switch?
The ABB OTL125B3U is a robust 125 A metal enclosed safety switch-disconnector designed to provide dependable local isolation of industrial machinery, motors and electrical distribution circuits. With ABB product ID 1SCA022562R9670, this three-pole unit combines reliable load-breaking performance with a rigid steel sheet enclosure for demanding industrial installations.
As part of the ABB OTL enclosed switch-disconnector series, the OTL125B3U features an IP65 alu-zinc coated steel sheet enclosure with polyester powder coating, a black pistol-type operating handle and an interlocked hinged door. The cover cannot normally be opened while the switch is ON, while the defeatable interlock permits 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 OTL125B3U is suitable for substantial industrial loads and motor isolation duties. Its three-pole configuration supports three-phase circuits, while the blank top and bottom cable entries can be drilled to suit the required installation.
