The OptiFuse CBW57-PS-30A is a thermal circuit breaker designed for reliable overcurrent protection. It offers a wide amperage range from 3A to 30A and supports input voltages of 125/250 VAC and 32/50 VDC, operating at 50-60 Hz.
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 is rated for 500 cycles at 150% of its rated current at 125 VAC. It also meets SAE J1171 and UL1500 standards for marine ignition protection.
This circuit breaker features a push-to-reset actuator and a panel mount design for easy integration into systems. The operating ambient temperature range is -10°C to +60°C. The body is black with tin-plated terminals.
Agency listings include UR (3A-30A, 125/250 VAC, 50 VDC), CCC (3A-20A, 125/250 VAC), TUV (3A-20A, 125/250 VAC, 32 VDC), and VDE (3A-16A, 125/250 VAC).
