The Schurter Inc. 4435.0129 is a 2-pole thermal-magnetic circuit breaker designed for equipment protection. It offers a rated voltage of 240 VAC (IEC) or 277 VAC (UL/CSA) and a DC voltage rating of 60 VDC.
This circuit breaker features rocker actuation and a thermal-magnetic tripping type, with a rated current range from 0.05 A to 20 A (magnetic up to 16 A). It has a conditional short circuit capacity of 2 kA at 240 VAC. The device operates within a temperature range of -30°C to 60°C and has a mechanical lifetime of 50,000 switching cycles.
Applications for this circuit breaker include power tools, medical and laboratory equipment, industrial appliances, equipment for construction, cleaning equipment, and commercial kitchen appliances. It is designed for panel mounting and offers a degree of protection of IP40 on the front side.
Key specifications include a dielectric strength greater than 2.5 kV at 50 Hz and greater than 4 kV for 1.2/50 μs impulses, with an insulation resistance greater than 100 MΩ at 500 VDC. The unit has a weight of 32 g (without magnet module) or 56 g (with magnet module).
It is rated for 240 VAC under IEC standards, 277 VAC under UL/CSA standards, and 60 VDC.
It uses a panel mount configuration.
The unit operates reliably between -30°C and 60°C.
It provides 2 kA of short-circuit capacity at 240 VAC per IEC 60934.
It features a two-pole design.
The breaker is rated for 50,000 switching cycles.
