OTP36A3M1 Safety switch

 

The OTP36A3M1 safety switch is a robust and reliable solution for low-voltage disconnect applications, specifically engineered to meet industrial safety standards. This 3-pole switch supports operational voltages up to 750V and delivers a rated operational current of 45A (AC-23A at 415V), making it suitable for demanding environments with power ratings reaching 22kW at AC-23A. The design incorporates a durable glass-reinforced polycarbonate enclosure, offering UV protection and an IP65 ingress rating according to IEC 60529, ensuring resistance against dust, water jets, and harsh conditions.

 

Its interlocked cover with defeatable interlocking enhances operator safety while allowing maintenance adaptability. The red-yellow selector handle meets international color-coding norms for clear visual identification during operation. Cable entry flexibility is supported by dual top/bottom cable outlets accommodating cross-sections in the range of 1.5–35 mm² and screw clamp terminal connections rated for reliable electrical integrity under high loads. Rated impulse withstand voltage reaches up to 1.5 kV, adhering to IEC/EN60664-1 standards.

 

Additional features include IK08 impact resistance on the housing, fixed neutral functionality, compatibility with auxiliary contacts (up to two NO/NC configurations), and compliance with pollution degree category III as defined by IEC standards. With certifications including CE Declaration of Conformity and DNV GL approval alongside adherence to IEC60947-1/-3 specifications for load break switches, this device aligns seamlessly with rigorous B2B technical requirements in sectors such as industrial automation, marine systems, or building infrastructure applications demanding high reliability and safety performance.
