The Schurter Inc. 4400.0415 is a thermal circuit breaker designed for equipment protection. It operates at a rated voltage of 240 VAC and 48 VDC, with a current rating range of 0.05 to 16 A. This 1-pole breaker features a push-to-reset actuation type and a panel mount design, making it suitable for various applications.
Key technical specifications include a conditional short circuit capacity of 2 kA at 240 VAC and a degree of protection of IP40. The dielectric strength is rated at over 1.5 kV (50 Hz) and over 2.5 kV (1.2/50 μs impulse). Insulation resistance is greater than 100 MΩ at 500 VDC.
This circuit breaker is built for durability, with typical endurance of 500 switching cycles at 2 x Ir and minimum endurance of 50 switching cycles for DC applications. It can withstand overload conditions, with a minimum of 40 trips at 6 x Ir for IEC standards and 50 trips at 1.5 x Ir for UL/CSA standards.
Environmental considerations include an operating temperature range of -5 °C to 60 °C. The device also exhibits resistance to vibration and shock, meeting IEC standards. Applications for this circuit breaker include power tools, household equipment, power supplies and chargers, and industrial appliances.
