This OptiFuse CBW68-HF-70A-5P is a thermal circuit breaker with a 70A current rating, suitable for 250VAC or 50VDC systems. It offers a push-to-reset actuator for convenient operation and a panel mount design for easy integration into equipment.
The circuit breaker is built for occasional overcurrent protection, featuring a dielectric strength of 1500 VAC for one minute and an insulation resistance greater than 500MΩ. Its contact endurance is rated for over 500 cycles at 125 VAC with 150% of the rated current. The reset time is less than 60 seconds.
Calibration specifications indicate that the device will hold at 100% of rated current, trip within 1 hour at 150% of rated current, and trip within 8.5-45.0 seconds at 200% of rated current. It is designed for standard profile applications and is intended for occasional overcurrent protection scenarios.
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 may damage device performance.
