The Schurter Inc. 4400.0573 is a thermal circuit breaker with a threaded neck type and quick connect terminals. It is designed for panel mounting and features a 1-pole configuration.
This circuit breaker operates at a rated voltage of 240 VAC and 48 VDC, with a rated current range of 0.05 to 16 A. It offers a conditional short circuit capacity of 2 kA at 240 VAC and a short circuit capacity (Icn) of 8 x In at less than 6.5 A and 96 A at 6.5 A or more. The degree of protection on the front side is IP40.
Key electrical specifications include a dielectric strength greater than 1.5 kV (50 Hz) and 2.5 kV (Impulse 1.2/50 μs), 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 under specific DC conditions. Overload protection is specified as a minimum of 40 trips at 6 x Ir for IEC standards and 50 trips at 1.5 x Ir for UL/CSA standards.
The operating temperature range is -5 °C to 60 °C. The device is resistant to vibration and shock according to IEC standards. Applications include power tools, household equipment, power supplies and chargers, and industrial appliances. It features a compact design and positively trip-free release.
The circuit breaker is rated for 240 VAC and 48 VDC.
The allowable operating temperature range is -5°C to 60°C.
The rated current is 600 mA (0.6 A).
It uses a push-to-reset actuator.
It is designed for panel mount installation.
Conditional short circuit capacity is 2 kA at 240 VAC. Short circuit capacity Icn is 8 x In for currents below 6.5 A, and 96 A for currents at or above 6.5 A at 240 VAC.
