The Schurter Inc. 3-128-232 is a TA36 series thermal circuit breaker designed for equipment protection. This 2-pole breaker features rocker actuation and a panel mount configuration.
Key electrical specifications include a rated current range of 0.05 to 20A AC (magnetic up to 16A) and a rated voltage of 240 VAC (IEC) or 277 VAC (UL/CSA). For DC applications, it supports 32 VDC for single-pole and 60 VDC for double-pole configurations. The conditional short circuit capacity is 2 kA at 240 VAC.
Environmental and mechanical characteristics include an operating temperature range of -30°C to 60°C and a degree of protection of IP40 on the front side. The breaker is built for durability with a mechanical lifetime of 50,000 switching cycles.
Applications for this circuit breaker include power tools, medical and laboratory equipment, industrial appliances, construction equipment, cleaning equipment, and commercial kitchen appliances. It provides thermal and thermal-magnetic tripping capabilities for reliable circuit protection.
The 3-128-232 is rated for 240 VAC (IEC) and 277 VAC (UL/CSA) for AC operation, and for DC: 32 VDC for 1-pole and 60 VDC for 2-pole.
It is a panel mount circuit breaker.
The allowable operating temperature range is -30°C to 60°C.
It is a thermal-magnetic tripping type.
The front side is rated IP40 according to IEC 60529.
It is approved by CCC, CE, cURus, and VDE.
The mechanical lifetime is 50,000 switching cycles for both 1- and 2-pole configurations.
