Why Choose the OTL45B3M [1SCA022562R4790]
This 3-pole, 45A enclosed switch disconnector is rated for 415V AC23 and 22kW applications. It features a robust steel sheet enclosure with a durable alu-zinc coating and polyester powder finish, ensuring corrosion resistance and suitability for outdoor environments. The enclosure is rated IP65, providing protection against dust and water ingress. A black selector handle offers clear operation, while the hinged door includes a lock for security. The interlocked cover prevents access when the switch is on, enhancing safety; however, the interlock can be overridden for thermographic inspection. Knock-out cable entries facilitate flexible wiring, and the unit includes neutral and PE terminals for comprehensive earthing and neutral connections. The enclosure complies with UL746C standards for UV exposure, water resistance, and immersion, making it reliable for demanding external installations.
