The Schurter Inc. 4411.0044 is a thermal circuit breaker with a threaded neck type and screw terminals. It features a compact design with a positively trip-free release mechanism and is available with a cover and different mounting possibilities.
This 1-pole breaker has a rated current of 17A and can handle AC voltages up to 277 VAC and DC voltages up to 28 VDC. It offers a conditional short circuit capacity of 1 kA (Inc) and a short circuit capacity (Icn) of 400 A at 28V AC/DC or for higher currents at 240V AC. The front side has an IP40 degree of protection according to IEC 60529.
Key technical data includes a dielectric strength of 1.5 kV at 50 Hz and > 2.5 kV impulse, with an insulation resistance greater than 100 MΩ at 500 VDC. Endurance is typically 3000 switching cycles. The allowable operating temperature range is -5 °C to 60 °C. It is designed for applications such as power supplies, uninterruptible power supplies, power tools, and household appliances.
The breaker is panel mounted and features a push-to-reset actuator type. It weighs approximately 10g. Approvals include CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077.
The circuit breaker is rated for 277VAC and 28VDC.
