BEP 185120P-01-1 Heavy Duty 120A Panel Mount Circuit Breaker

BEP / Bussmann 120A Heavy-Duty Panel Mount Circuit Breaker (185120P-01-1)

The BEP 185120P-01-1 (utilizing the Cooper Bussmann 185 Series architecture) is a high-amperage, heavy-duty 120A Panel Mount Thermal Circuit Breaker engineered to provide overcurrent protection for main DC distribution systems, heavy windlasses, high-capacity inverter banks, bow thrusters, and secondary power feeds. Operating across DC systems up to 48 V DC (12V, 24V, 36V, and 48V), it functions as both an automatic circuit breaker and a manual battery disconnect switch via its trip lever.

Built for harsh operating environments, the 185120P-01-1 features a high-impact thermoset plastic casing sealed to IP67 standards, making it impervious to direct water spray, dust, and salt-air corrosion. It is fully ignition protected (SAE J1171 / UL 1500), making it safe for installation in gasoline engine bays and battery enclosures. The panel mount flange layout provides a clean, flush-through mounting profile with immediate visual status indication.
