Mastervolt 70905380 80A Double Pole CD Rocker Breaker

Mastervolt 70905380 Double Pole CD Rocker Circuit Breaker (80A - Red)

The Mastervolt 70905380 is a commercial/marine grade 80 A double-pole hydraulic-magnetic circuit breaker featuring a red illuminated CD-style rocker actuator. Engineered specifically for integration into Mastervolt MasterVision modular switchboards and heavy-duty DC power distribution networks, this breaker provides overcurrent circuit protection and positive isolation for high-amp load circuits like battery chargers, sub-panels, and inverter feeds.

Unlike thermal breakers, its hydraulic-magnetic tripping mechanism is unaffected by ambient temperature variations in engine rooms or battery lockers, maintaining precision current handling from -40°C to +85°C. The double-pole configuration opens both positive and negative conductors simultaneously (or dual positive legs), while the high-visibility red CD rocker switch offers clear ON/OFF status identification.

Key Features

• Hydraulic-Magnetic Trip Technology: Delivers consistent trip calibration across extreme temperature ranges without nuisance tripping caused by elevated ambient heat.

• Double-Pole Simultaneous Trip: Disconnects two isolated lines simultaneously for safety compliance on marine DC/AC systems.

• MasterVision Modular Native: Fits into Mastervolt MasterVision panel cutouts for seamless distribution panel buildouts.

• High Interrupt Capacity: Safely handles high fault currents on heavy-duty DC battery banks.
