1SCA022562R8600 ABB Steel Enclosed Switch-Disconnector 100 A 4 Pole

Why Choose the ABB OTL100B4U Enclosed Switch-Disconnector?

The ABB OTL100B4U is a robust steel enclosed switch-disconnector designed to provide dependable local isolation of industrial machinery, distribution circuits and electrical loads. With ABB product ID 1SCA022562R8600, this four-pole unit combines a 100 A rating, reliable load-breaking performance and a rigid steel enclosure for demanding industrial installations.

As part of the ABB OTL enclosed switch-disconnector series, the OTL100B4U features an IP65 steel sheet enclosure with a black pistol-type operating handle, hinged door and cover interlock. The interlocking system prevents the enclosure from being opened while the switch is in the ON position, while a defeatable interlock allows authorised access when required for procedures such as thermographic inspection.

The OTL100B4U provides 100 A AC-22A switching at 380–415 V and 80 A AC-23A switching at 380–415 V, corresponding to a motor switching capability of 37 kW at 415 V. Its four-pole configuration, blank cable-entry arrangement and included neutral and PE terminals make it a flexible solution for industrial power isolation and machinery applications.
