Bryant BR390 Circuit Breaker

Bryant BR390 is a Type BR molded‑case circuit breaker rated for 90 A at 240 V, configured as a three‑pole device with a common trip for all phases. It uses a thermal‑magnetic trip mechanism and carries a 10 kA interrupting rating (10,000 AIC) at 240 VAC, enabling safe interruption of fault currents. The BR390 is a plug‑on, 1‑inch‑per‑pole device designed for use in BR‑type load centers and compatible panels, providing reliable three‑phase protection for larger circuits. With a 90 A rating, it is commonly employed to safeguard heavy loads such as HVAC equipment, motors, pumps, compressors, and distribution panels in residential, commercial, and light industrial electrical systems. As part of the BR family, this breaker supports coordinated trip performance within compatible panels, ensuring all three phases disconnect together in fault conditions.
