The Schurter Inc. 4404.0062 is a thermal circuit breaker designed for equipment protection. It is a single-pole device with a snap-in mounting type suitable for panel installation.
Key electrical specifications include a rated AC voltage of 240 VAC and a rated DC voltage of 48/32 VDC. The current rating ranges from 3A to 16A. It offers a conditional short circuit capacity of 2 kA at 240 VAC and 2 kA at 48/32 VDC. The breaker is designed with a push-to-reset actuator and features cycling trip-free release.
Environmental protection is rated at IP40 for the front side. The device has an endurance rating of a minimum of 50 switching cycles under IEC conditions and typically 2500 switching cycles for 3-8A ratings, and 6000 switching cycles for 10-16A ratings. Operating temperature ranges vary slightly by current rating, generally from -5°C to 60°C.
This circuit breaker is designed according to standards such as IEC 60934 and UL 1077. It is suitable for applications including power supplies, uninterruptible power supplies, power tools, industrial appliances, HVAC, and household appliances.
The rated AC voltage is 240 VAC and the rated DC voltage is 48/32 VDC.
The datasheet specifies a rated current range of 3-16 A depending on approbations; this part is identified as a 16 A breaker.
For 3 A and 5-16 A ratings, the allowable operating temperature is -5 °C to 60 °C; for 4 A ratings, it is -5 °C to 50 °C.
Approvals include CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077.
It has a push-to-reset actuator and is panel mounted.
Dielectric strength is 1500 VAC, and insulation resistance is greater than 1000 MΩ at 500 VDC.
The front-side degree of protection is IP40.
