The OptiFuse CBW57-PB-15A-5X is a thermal circuit breaker designed for overcurrent protection. It offers a current rating range of 3A to 30A, with this specific model rated at 15A. The breaker operates at 250 VAC and 32 VDC, with a frequency range of 50-60 Hz.
Key electrical specifications include an interrupt rating of 1000A at 125/250 VAC and 400A at 125/250 VAC for 3-20A models, and 300A at 50 VDC for 3-30A models. It also features a dielectric strength greater than 1500 VAC and insulation resistance over 100MΩ (500 VDC). The contact endurance is rated for 500 cycles at 125 VAC with 150% of rated current.
This circuit breaker has a push-to-reset actuator and a panel mount type. The operating ambient temperature range is -10°C to +60°C. It is ignition protected to SAE J1171 and UL1500 standards. Agency listings include UR, CCC, TUV, and VDE, covering various voltage and current ratings.
Designed for occasional overcurrent protection, this device is intended for applications where prolonged trip conditions are not anticipated. It is important to avoid contact with chemical solvents, which can damage the device's performance.
