OT75ETUU3TE Safety switch

The OT75ETUU3TE is a robust EMC safety switch designed for demanding industrial applications, offering reliable performance and compliance with international standards. It operates as a 3-pole switch rated for up to 415V AC23, with an operational current of 80A and power-switching capability of 37kW. Its polyester powder-coated steel sheet enclosure provides enhanced durability and environmental resistance, achieving an IP65 protection rating against dust and water ingress and an IK09 impact resistance rating.

 

Key features include defeatable interlocking for secure operation, a black pistol handle for ergonomic handling, and mounted auxiliary contacts configured as 1NO/0NC. The device’s cable entry positions are located at the top or bottom, supporting wire cross-sections between 10 to 70 mm² via screw clamps. Rated insulation voltage reaches up to 750V according to IEC/EN60664-1 standards. The enclosure adheres to pollution degree level 3 regulations per IEC60529.

 

This safety switch meets IEC60947-1/-3 standards regarding electrical equipment functionality and reliability while providing short-circuit making capacities up to 3.6 kA at 690V AC and thermal current capacity enclosed at 115 A. Operational efficiencies include low power loss per pole—4 W under full load—and precise torque requirements of main circuit terminals (6 N·m). Additional technical certifications cover CE conformity alongside compliance with RoHS Directive amendments.

 

Weighing only ~3 kg with compact dimensions (200mm x 300mm x135mm), the OT75ETUU3TE ensures straightforward integration into control systems across diverse industrial sectors like automation, infrastructure projects, oil & gas installations, marine systems, or energy generation setups requiring dependable disconnection or isolation solutions compliant with B2B operational demands.
