This Schurter Inc. 4400.0019 is a thermal circuit breaker with a single pole configuration, suitable for panel mounting. It features quick connect terminals for easy integration into systems.
The device operates with a rated AC voltage of 240 VAC and a rated DC voltage of 48 VDC, with a rated current range from 0.05 to 16 A. It has a conditional short circuit capacity of 2 kA and a short circuit capacity (Icn) of 8 A or 96 A depending on the current rating. The circuit breaker is designed for a wide operating temperature range of -5 °C to 60 °C.
Key specifications include a dielectric strength greater than 1.5 kV (50 Hz) and 2.5 kV (1.2/50 μs impulse), and an insulation resistance greater than 100 MΩ at 500 VDC. Endurance is rated at a typical 500 switching cycles and a minimum of 50 switching cycles for reset types. Overload endurance meets IEC standards with a minimum of 40 trips at 6 x Ir and UL/CSA standards with a minimum of 50 trips at 1.5 x Ir.
Applications for this thermal circuit breaker include power tools, household equipment, power supplies and chargers, and industrial appliances. It offers a compact design with positively trip-free release and various mounting possibilities.
The allowable operating temperature range is -5°C to 60°C.
The rated voltage is 240 VAC and 48 VDC.
The degree of protection is IP40 according to IEC 60529.
It uses a push-to-reset actuator.
The mounting type is panel mount.
