The OptiFuse CBW57-PS-5A-1X is a thermal circuit breaker with a current rating range of 3A to 30A, and specifically this model is rated at 5A. It operates with input voltages of 125/250 VAC and 32/50 VDC, at frequencies of 50-60 Hz. The breaker offers a dielectric strength greater than 1500 VAC and an insulation resistance over 100MΩ (500 VDC).
Designed for reliability, it has a contact endurance of 500 cycles at 150% of rated current and a reset time within 60 seconds. The operating ambient temperature range is -10°C to +60°C. This model features a push-to-reset actuator and a panel mount type, with a black body and tin-plated terminals.
Agency approvals include CCC, CSA, cURus, TUV, UR, and VDE, indicating broad compliance for various applications. The interrupt rating varies by current and voltage, with up to 1000A at 125/250 VAC for 3-30A ratings. It is also CSA Marine Ignition Protected to SAE J1171 and UL1500.
This circuit breaker is intended for occasional overcurrent protection and should not be used for repeated overcurrent conditions. Avoid contact with chemical solvents, as prolonged contact can damage performance.
