1SCA022571R9310 ABB 36A 3P 18.5 kW Enclosed Safety Switch

Why Choose the ABB OTL36T3B 36A 3-Pole 18.5 kW Enclosed Safety Switch?

The ABB OTL36T3B, order code 1SCA022571R9310, is a robust 36 A three-pole 18.5 kW enclosed safety switch designed for dependable load breaking and electrical isolation of industrial motors, machinery and electrical equipment. As part of ABB's Metal Enclosed (Loadbreak) product group, it combines reliable switching performance with a durable steel-sheet enclosure for demanding industrial installations.

Designed for local safety isolation, the OTL36T3B features a black I-O / ON-OFF selector handle, together with a grey steel-sheet enclosure equipped with hinges and a lock. The cover is interlocked to help prevent normal opening while the switch is in the ON position, and the interlock can be defeated when authorised access is required. An included 1 NO auxiliary contact supports signalling and associated control functions.

With an authoritative rating of 36 A, an 18.5 kW motor rating and a three-pole configuration, the OTL36T3B provides reliable local isolation for three-phase industrial equipment. Its IP65 steel-sheet enclosure, bottom cable-entry arrangement and compact 200 × 150 × 100 mm dimensions make it practical for installation alongside machinery and other electrical equipment.
