Why Choose the OTL16T3B [1SCA022571R9150]
This 3-pole safety switch is rated for 415V AC23, 16A, and 7.5kW applications. It features a mounted auxiliary contact with one normally open (1NO) and one normally closed (1NC) contact. The enclosure is constructed from rigid alu-zinc coated steel with a durable polyester powder coating, providing IP65 protection. Designed for secure operation, the black selector handle includes an interlocked cover that prevents opening while the switch is on; this interlock can be overridden when required for thermographic testing. The hinged door incorporates a lock for added security. Suitable for outdoor installation, the enclosure complies with UL746C standards for UV resistance, water exposure, and immersion. Cable entries are knock-out type, and a PE terminal is provided for reliable earthing.
