The OptiFuse CBW57-AS-8A is a low-profile thermal circuit breaker designed for overcurrent protection. It offers an amperage 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 100M Ω, and various interrupt ratings depending on current and voltage. The breaker features a push-to-reset actuator and a tin-plated terminal finish.
This circuit breaker has a panel mount type and an operating ambient temperature range of -10℃ to +60℃. It is listed by multiple agencies including UR, CCC, TUV, and VDE, ensuring compliance with various industry standards.
Designed for occasional overcurrent protection, the CBW57-AS-8A is suitable for applications requiring reliable circuit interruption. Avoid contact with chemical solvents, as prolonged exposure can degrade performance.
The breaker is rated for 8A continuous current and accepts 125/250 VAC (50-60 Hz) or 32/50 VDC.
The operating ambient temperature range is -10°C to +60°C.
Interrupt ratings vary: 1000A @ 125/250 VAC for 3-30A, 400A @ 125/250 VAC for 3-20A, 300A @ 50 VDC for 3-30A, and 400A @ 125 VAC for 3-20A.
At 25°C: no trip at 100% rated current, trip within 1 hour at 150%, trip between 5-30 seconds at 200%, and trip between 1.5-5 seconds at 300%.
The breaker is rated for 500 cycles at 125 VAC and 150% of rated current.
It is approved by CCC, CSA, cURus, TUV, UR, and VDE. It also meets marine ignition protection standards SAE J1171 and UL1500.
