FAQs
The BRF120 uses a plug-on mounting method designed for BR-series panels. It is a single-pole device rated for 120/240 V with 20 A capacity and a 10 kAIC interrupt rating. Ensure enclosure space is sufficient (approximately 3 in x 3 in x 2 in working footprint), and verify compatibility with existing BR main breakers for safe, code-compliant retrofits.
A 10 kAIC interrupt rating indicates the breaker can safely interrupt fault currents up to 10,000 amperes. This improves protection in installations with higher fault-current potential, reducing the risk of equipment damage and enhancing overall panel resilience in moderate to high fault scenarios.
Yes. The BRF120 is a Type BRF plug-on fire alarm circuit breaker designed to protect dedicated fire alarm circuits while meeting NFPA 72 life-safety requirements.its HACR rating further supports HVAC-related control circuits, helping to ensure reliable operation of critical alarms.
The unit lists HACR rated compliance and NFPA 72 as applicable standards. Certifications beyond these are available from the manufacturer, and detailed documentation can be requested to satisfy specific regulatory or end-user requirements during procurement.
The BRF120 carries a 1-year warranty. For maintenance, rely on standard inspection for torque, contact wear, and proper plug-on seating in the panel. This short-term coverage supports procurement planning and reduces lifecycle risk for fire-alarm and control circuits.
