The OptiFuse CBW28-4A is a thermal circuit breaker designed for reliable overcurrent protection in various applications. This component features a 4A current rating and a 250V AC voltage rating, suitable for many electrical systems.
Key specifications include a thermal breaker type with a push-to-reset actuator, allowing for easy manual reset after a trip. It is a single-pole device designed for a panel thickness range of 0.8 – 2.1mm, utilizing a snap-in front panel mount for secure installation. The circuit breaker offers an interrupt capacity of 1000A at 250 VAC.
Additional electrical characteristics include an insulation resistance of 100MΩ and quick connect terminals measuring 0.250” (6.35mm) with nickel-plated brass construction. The device is intended for occasional overcurrent protection and should not be used for repeated overcurrent conditions.
Note that all specifications are subject to change without notice. Proper use is essential to avoid damage, electrical arcing, or flame.
