The Schurter Inc. 4404.0097 is a single-pole thermal circuit breaker designed for through-hole mounting on PCBs. It offers a rated current of 4A and a rated voltage of 240 VAC, with a DC rating of 32 VDC. This breaker type is thermal, featuring a push-to-reset actuator and a cycling trip-free release mechanism.
Key technical specifications include a conditional short circuit capacity of 2 kA (AC and DC), an ingress protection rating of IP40 on the front side, and a dielectric strength of 1500 VAC. The insulation resistance is rated at over 1000 MΩ at 500 VDC. Endurance specifications vary based on current and power factor, with minimum IEC endurance at 50 switching cycles and typical endurance ranging from 2500 to 6000 switching cycles.
Operating temperature ranges from -5°C to 60°C for most current ratings, with a specific range of -5°C to 50°C for the 4A rating. The component supports wave soldering with solderability at 245°C for 3 seconds and resistance to soldering heat at 260°C for 10 seconds. Approvals include CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077.
