The Schurter Inc. 4404.0008 is a thermal circuit breaker designed for equipment protection. It is a single-pole device with a snap-in mounting type, allowing for front-side installation on panels from 0.8 to 2.0mm thick. This circuit breaker has a rated current of 14A and can handle AC voltages up to 240 VAC and DC voltages up to 32 VDC.
Key electrical specifications include a conditional short circuit capacity of 2 kA at 240 VAC (IEC 60934: PC1) and 2 kA at 48/32 VDC (UL/CSA: C1). The device offers a dielectric strength of 1500 VAC and an insulation resistance greater than 1000 MΩ at 500 VDC. Endurance ratings vary by current, with typical values of 2500 switching cycles for 3-8A and 6000 switching cycles for 10-16A at 150% Ir, cos φ 0.9.
Environmental and thermal data include a front-side degree of protection of IP40. Allowable operating temperatures range from -5°C to 60°C for 3A and 5-16A ratings, and -5°C to 50°C for the 4A rating. The circuit breaker weighs between 9 and 13 grams.
Applications for this thermal circuit breaker include power supplies, uninterruptible power supplies, power tools, industrial appliances, HVAC systems, and household appliances. It is designed according to standards such as IEC 60934 and UL 1077.
