Why Choose the OTL75T3B [1SCA022546R0820]
This 3-pole safety switch is rated at 415V AC23, 80A, with a power capacity of 37kW. It features a mounted auxiliary contact configuration of 1NO and 1NC for status signalling. The enclosure is constructed from rigid alu-zinc coated steel with a durable polyester powder finish, providing robust protection and corrosion resistance. Designed to IP65 standards, the unit is suitable for outdoor installation, offering protection against dust ingress and water jets, and complies with UL746C for UV exposure, water contact, and immersion. The hinged steel door includes a lock and an interlocked cover mechanism that prevents opening while the switch is on, enhancing operational safety; this interlock can be overridden for thermographic inspections. Cable entries are knock-out type for flexible wiring options, and a protective earth (PE) terminal is included. The black pistol handle ensures clear, ergonomic operation in demanding environments.
