The OptiFuse CBW57-EJ-30A is a thermal circuit breaker designed for overcurrent protection. It operates within an amperage range of 3A to 30A and has a voltage rating of 125/250 VAC and 32/50 VDC.
Key electrical specifications include a dielectric strength greater than 1500 VAC, an interrupt rating of up to 1000A at 125/250 VAC, and insulation resistance exceeding 100MΩ at 500 VDC. The breaker offers a reset time within 60 seconds and contact endurance of 500 cycles at 125 VAC with 150% of rated current.
This circuit breaker features a push-to-reset actuator and a panel mount design. The operating ambient temperature range is -10°C to +60°C. It is listed by UR and cURus agencies.
Applications include general overcurrent protection where a thermal tripping mechanism is required. The device is intended for occasional overcurrent protection and not for repeated overcurrent conditions.
The current rating is 30A.
The maximum AC voltage rating is 250 VAC.
The operating ambient temperature range is -10°C to +60°C.
It features a push-to-reset actuator and has a reset time within 60 seconds.
It is listed by UR and cURus agencies.
