The ABB OTL75T3B (1SCA022546R0820) is a robust 3-pole enclosed safety switch designed to provide reliable electrical isolation for industrial machinery, power distribution systems and commercial installations. As part of the proven ABB OTL enclosed safety switch series, it offers safe manual isolation of electrical circuits whilst protecting personnel during maintenance and servicing operations.
Built within a durable steel enclosure with a polyester powder-coated finish, the OTL75T3B is engineered to withstand demanding industrial environments. Its hinged, lockable door incorporates an interlocked mechanism that prevents the enclosure from being opened while the switch is energised, enhancing operator safety. The enclosure also offers IP65 protection, making it suitable for both indoor and outdoor installations.
Rated for 80 A at 380-415 V AC (AC-23A) with a switching capacity of 37 kW, the OTL75T3B is ideal for isolating motors, machinery, pumps, HVAC equipment and industrial power supplies. The unit includes 1 NO and 1 NC auxiliary contacts for signalling and control applications.
Enclosed safety switches provide a secure means of disconnecting electrical equipment from the power supply during servicing, inspection and maintenance. They help protect maintenance personnel while ensuring machinery remains safely isolated before work begins.
The ABB OTL75T3B combines a heavy-duty switch disconnector with a weather-resistant enclosure, making it suitable for industrial manufacturing, utilities, commercial buildings and outdoor electrical installations where dependable isolation is essential.
