The OptiFuse CBW57-ES-10A-5H is a low-profile thermal circuit breaker designed for overcurrent protection. It offers a current rating range from 3A to 30A, with this specific model rated at 10A.
This circuit breaker operates with input voltages of 125/250 VAC and 32/50 VDC, at frequencies of 50-60 Hz. It boasts a high dielectric strength of over 1500 VAC and an insulation resistance greater than 100MΩ (500 VDC). The device is ignition protected to SAE J1171 and UL1500 standards, making it suitable for marine applications.
Key features include a push-to-reset actuator, a black body with tin-plated terminals, and a panel mount design. The operating ambient temperature range is -10°C to +60°C. The CBW57 series is agency listed by UR, CCC, TUV, and VDE, indicating broad compliance for various applications.
This breaker is intended for occasional overcurrent protection and should not be used for repeated overcurrent conditions. Avoid contact with chemical solvents, as prolonged exposure can degrade performance.
