The Schurter Inc. 4404.0103 is a thermal circuit breaker designed for equipment protection. It features THT terminals for PCB mounting and a compact design with a push-to-reset actuator. This 1-pole breaker operates at a rated voltage of 240 VAC and has a rated current of 12A. It offers a conditional short circuit capacity of 2 kA under various conditions (IEC, UL/CSA). The device is designed for through-hole mounting and has an IP40 degree of protection on the front side. 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.
Applications for this circuit breaker include power supplies, uninterruptible power supplies, power tools, industrial appliances, HVAC systems, and household appliances. It meets product standards such as IEC 60934, UL 1077, and CSA C22.2 No. 235. The operating temperature range is typically -5°C to 60°C, depending on the current rating. Solderability and resistance to soldering heat are specified according to IEC standards, with a weight of approximately 12.5g.
Rated voltage AC is 240 V, rated voltage DC is 48 V and 32 V.
For 5-15 A rating, the allowable operating temperature is -5 °C to 60 °C.
