The SunGold Power 400 Amp DC Breaker (DHM1B-400) is a heavy-duty battery disconnect switch and DC circuit breaker. Its thermal magnetic trip mechanism protects against overloads and short circuits, and it isolates the battery bank when you need to service the system.
SunGold uses 400A DC breakers in its larger kits, such as the 12kW, 15kW, and 18kW off-grid systems, where inverter battery currents are highest. SunGold also lists it for marine uses such as boat trolling motor circuits.
Protects high-current battery cables from sustained overloads and short circuits.
Switch off to isolate large battery banks for maintenance or emergencies.
Installs in compartments with front access for easy operation.
Large inverter systems. Protect the battery to inverter connection on 12kW to 18kW systems.
Marine systems. Use as a battery disconnect for high-current marine loads.
