BEP 185040P/DSP 40A Heavy Duty Circuit Breaker

BEP Marine 40A Heavy-Duty Switch-Settable Circuit Breaker (185040P/DSP)

The BEP 185040P/DSP (retail display package SKU for base part 185040P) is a high-capacity, surface/panel-mount 40 Amp thermal DC circuit breaker designed for heavy-duty marine, commercial vehicle, and off-grid power distribution. It serves the dual purpose of protecting high-current DC circuits against overcurrent faults while functioning as a manual circuit isolation switch.

Engineered with a high-impact, weather-resistant composite housing, the 185040P features a prominent manual reset lever with an integrated "Trip" mechanism. The unit is rated for DC operating voltages up to 48V DC with an interrupt capacity of 3,000 A at 48V, making it ideal for protecting trolling motors, windlasses, secondary battery banks, and sub-feed distribution panels.

Key Features

• Dual Circuit Protection & Manual Switch Function: Functions both as an automatic thermal trip device and a manual battery disconnect switch.

• Visible Reset Lever with Manual Trip: Red reset lever clearly indicates tripped status and can be manually switched off to isolate downstream circuits.

• High Interrupt Capacity: 3,000 A interrupt rating at 48V DC prevents arc flash weld during heavy dead-short conditions.

• Ignition Protected (SAE J1171): Safe for installation in marine engine compartments and gasoline fuel-vapor environments.

• Weatherproof IP67 Construction: Sealed housing with insulated terminal studs resists saltwater corrosion and washdown spray.
