The Schurter Inc. 4411.005 is a thermal circuit breaker with a threaded neck type and reset functionality. It is designed for panel mounting and features screw terminals.
This 1-pole breaker operates with a rated AC voltage of 240/277 VAC and a DC voltage of 28 VDC. The rated current range is from 0.05 to 30 A. It offers a conditional short circuit capacity of 1 kA at 240 VAC and a short circuit capacity (Icn) of 8 x In for currents less than 7 A, and 400 A for currents 7 A or greater at 240 VAC, and 400 A at 28 VDC.
Key technical data includes an operating temperature range of -5 °C to 60 °C, dielectric strength of 1.5 kV (50 Hz) and > 2.5 kV (1.2/50 μs impulse), and insulation resistance greater than 100 MΩ at 500 VDC. Endurance is typically 3000 switching cycles at 2 x Ir, with a minimum of 50 switching cycles under specific DC conditions.
Applications for this circuit breaker include power supplies, uninterruptible power supplies, power tools, and household appliances. It boasts a compact design and positively trip-free release.
The circuit breaker is rated for 240/277 VAC and 28 VDC.
