The Schurter Inc. 4404.0059 is a thermal circuit breaker designed for equipment protection. It features a snap-in mounting type suitable for front-side installation on panels with thicknesses from 0.8 to 2.0mm. This 1-pole breaker operates with a rated voltage of 240 VAC and 48/32 VDC, and has a rated current range of 3-16 A, with this specific model rated at 10A.
Key electrical specifications include a conditional short circuit capacity of 2 kA (IEC/UL/CSA) and a degree of protection of IP40 on the front side. The breaker offers a dielectric strength of 1500 VAC and an insulation resistance greater than 1000 MΩ at 500 VDC. It is designed for a minimum of 50 switching cycles under IEC conditions and typically 2500 switching cycles for 3-8A ratings or 6000 for 10-16A ratings.
Thermal performance is characterized by an allowable operating temperature range of -5°C to 60°C for most current ratings, with a slightly lower range for 4A models. The breaker has a compact design and features a push-to-reset actuator with a cycling trip-free release mechanism. It is approved by CSA, EN, GB, IEC, and UL standards, making it suitable for various industrial applications such as power supplies, uninterruptible power supplies, power tools, industrial appliances, HVAC systems, and household appliances.
