The OptiFuse CBW57-PF-5A-5X is a thermal circuit breaker with a 5A current rating and a 250VAC / 32VDC voltage rating. It is designed for panel mounting and features a convenient push-to-reset actuator. This breaker operates within a frequency range of 50-60 Hz and offers a dielectric strength greater than 1500 VAC.
Key electrical specifications include an interrupt rating of 1000A at 125/250 VAC and 400A at 125 VAC. The insulation resistance is rated above 100MΩ (at 500 VDC), and it has a contact endurance of 500 cycles at 125 VAC with 150% of rated current. The operating ambient temperature range is from -10°C to +60°C.
This circuit breaker is listed by several agencies, including UR, CCC, TUV, and VDE, ensuring compliance with various industry standards. It is suitable for applications requiring reliable overcurrent protection where a thermal tripping mechanism is preferred. The device is intended for occasional overcurrent protection and not for repeated overcurrent conditions.
