The OptiFuse CBW28-5A is a thermal circuit breaker with a 5A current rating and a 250V voltage rating. It is designed for push-to-reset operation and features a snap-in front panel mount for easy installation. The breaker has a 1000A interrupt capacity at 250 VAC and 200A at 32 VDC. Its terminals are 0.250” [6.35mm] quick connect, nickel-plated brass. The panel thickness accommodation is 0.8 – 2.1mm.
This circuit breaker is suitable for occasional overcurrent protection. It is important to note that operation beyond the specified maximum ratings or improper use may result in damage, electrical arcing, or flame. Avoid contact with chemical solvents, as prolonged contact can damage device performance. The device is intended for use within specified temperature ranges, and ambient temperature correction factors may apply to prevent nuisance tripping.
Agency standards and listings include CSA and cULus. The insulation resistance is rated at 100MΩ. Calibration data specifies trip characteristics at various current percentages and timeframes, ensuring reliable protection within its operational limits.
