Noark Battery Breaker DC 3 Pole

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. Key Features 3-Pole DC Switching 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 in: LiFePO₄ battery systems High-voltage DC battery systems Off-grid power systems Commercial and industrial DC power systems Solar and energy storage systems High-current inverter and inverter/charger installations The three-pole configuration is particularly useful where multiple breaker poles are required to achieve the necessary DC voltage rating or where the system design requires simultaneous switching of multiple DC conductors.
