Noark Battery Breaker DC 2 Pole

Quantity

The Noark Ex9MD1B is a heavy-duty, resettable DC moulded-case circuit breaker designed for battery and other high-current DC applications.

Its two-pole design allows both conductors to be switched and isolated simultaneously, providing a convenient single-point disconnect for DC battery systems. Thermal-magnetic protection provides reliable overcurrent and short-circuit protection, while the resettable mechanism eliminates the need to replace fuses after an overload trip.

Key Features

2-Pole DC Switching & Isolation
Thermal-Magnetic Overcurrent Protection
High DC Interrupt Capacity
Resettable Design – no replacement fuses required
Heavy-Duty Lug Terminals for large battery cabling
Compact MCCB Construction
Suitable for frequent manual isolation and system servicing
Available in multiple current ratings

Typical Applications

Ideal for use as a main battery breaker in:

LiFePO₄ battery systems
Off-grid power systems
Caravan and motorhome electrical systems
Marine electrical systems
Commercial and industrial DC power systems
High-current inverter and inverter/charger installations

A practical alternative to high-current battery fuses where overcurrent protection, manual isolation and reset capability are required in a single device.
