Noark Battery Breaker DC 3 Pole
The Noark Ex9MD1B 3 Pole is a heavy-duty, resettable DC moulded-case circuit breaker designed for battery and other high-current DC applications.
Its three-pole design provides additional flexibility for higher-voltage DC systems and applications requiring multiple poles to be switched simultaneously. Thermal-magnetic protection provides reliable overcurrent and short-circuit protection, while the resettable mechanism eliminates the need to replace fuses after an overload trip.
