ABB SACE F3 F3S CIRCUIT BREAKER, SACE PR1/P

Product Overview

The ABB SACE F3 F3S paired with SACE PR1/P is a low voltage air circuit breaker engineered for industrial power distribution protection, designed in accordance with IEC low voltage standard and ABB SACE Megamax F series specification. Built for overcurrent protection, short-circuit interruption & power network monitoring, the circuit breaker withstands heavy fault current impact, delivers stable continuous operation, and provides reliable busbar and generator protection for power plants, factory substations and marine electrical distribution systems.

Featuring draw-out frame structure, PR1/P electronic protection relay & high-performance arc extinguishing chamber. Both fixed and withdrawable cabinet mounting are supported, adapting to limited space inside power distribution switchrooms and main electrical panels. The modular assembly allows separate replacement of protection relay or contact assembly without full busbar power cut, greatly reducing equipment downtime for service. Equipped with adjustable protection settings, trip status indication & fault recording function, mature interlock structure prevents misoperation and guarantees safe power system operation during continuous duty.

For dependable overcurrent protection, short-circuit interruption & power network monitoring, this ABB circuit breaker monitors load current and triggers rapid tripping upon overload and short-circuit faults. Reliable overcurrent protection, short-circuit interruption & power network monitoring, premium contact materials provide excellent arc erosion resistance, extending service life in harsh industrial working environments. Practical adjustable protection settings, trip status indication & fault recording function, precise electronic relay control lowers false tripping risk during long-hour operation, ensuring stable power supply under variable load conditions.

During continuous overcurrent protection, short-circuit interruption & power network monitoring, this breaker unit is widely fitted for main incoming feeders and generator output circuits, also compatible with low voltage power distribution networks. Stable overcurrent protection, short-circuit interruption & power network monitoring, mature ABB SACE Megamax technology with easy spare parts replacement and convenient after-sales maintenance. Robust adjustable protection settings, trip status indication & fault recording function, simplifies switchboard layout and reduces installation workload for facility retrofitting and power distribution overhaul projects.
