The OptiFuse CBW28-1A is a thermal circuit breaker with a 1A current rating and a 250V AC / 32V DC voltage rating. It is designed for push-to-reset operation and offers a breaking capacity of 1000A at 250 VAC and 200A at 32 VDC. The circuit breaker has a panel thickness compatibility of 0.8 – 2.1mm and utilizes 0.250” quick connect terminals.
This device is intended for occasional overcurrent protection and is approved by CSA and cULus. It features a snap-in front panel mount for easy installation. The thermal tripping characteristics vary based on current rating, with specific trip ranges defined for 1A-2.5A and 3.0A-16A ranges. Ambient temperature can affect performance, requiring derating factors for accurate operation.
Warning: Operation beyond specified maximum ratings or improper use may result in damage, electrical arcing, or flame. Avoid contact with chemical solvents, as prolonged contact can degrade device performance.
