The Littelfuse FA2-P0-14-840-22B-BT is a magnetic hydraulic delay circuit breaker rated for 400A continuous current at 277V. It is a 2-pole device, allowing simultaneous switching of two lines, and uses a lever actuator for manual reset. The hydraulic delay mechanism provides time-delayed tripping, accommodating inrush currents without nuisance tripping.
This circuit breaker is designed for chassis mount installation, making it suitable for power distribution panels, industrial equipment, and commercial building protection. It is approved by CCC and UL489A, ensuring compliance with international safety standards. The product is RoHS3 compliant, MSL level 1 unlimited, and REACH unaffected, though these compliance statuses are based on unverified data.
The non-illuminated lever actuator provides clear visual indication of the breaker state. The compact design supports integration into various electrical systems requiring overcurrent protection.
