The OptiFuse CBW57-HS-15A-5X is a thermal circuit breaker designed for overcurrent protection. It offers a current rating range of 3A to 30A and operates at 125/250 VAC and 32/50 VDC.
Key electrical specifications include a dielectric strength greater than 1500 VAC, an insulation resistance over 100MΩ (500 VDC), and a contact endurance of 500 cycles at 125 VAC with 150% of rated current. The reset time is within 60 seconds.
This circuit breaker features a push-to-reset actuator and a black body with tin-plated terminals. It is designed for panel mounting and operates within an ambient temperature range of -10℃ to +60℃. Agency standards and listings include UR, CCC, TUV, and VDE.
Applications for this device include general overcurrent protection where occasional overcurrent events are anticipated. It is important to avoid contact with chemical solvents, as prolonged contact can damage performance.
