The OptiFuse CBW28-8A is a thermal circuit breaker designed for overcurrent protection. It operates at a voltage rating of 250V and has a current rating of 8A. This breaker features a convenient push-to-reset actuator for easy operation.
Designed for front panel installation, the CBW28-8A utilizes a snap-in mounting type, suitable for panel thicknesses between 0.8mm and 2.1mm. The terminals are 0.250-inch quick connects made of nickel-plated brass. The breaker offers an interrupt capacity of 1000A at 250 VAC and 200A at 32 VDC.
Specifications include an insulation resistance of 100MΩ. The datasheet also details trip specifications, indicating when the breaker may trip or must trip at various percentages of its rated current. Ambient temperature correction factors are provided to adjust performance based on environmental conditions, helping to prevent nuisance tripping. Warnings advise against exceeding maximum ratings or improper use, as this may lead to damage or electrical arcing.
