Product Description

The Suntree SM1/SM8 series MCCBs are robust, thermal-magnetic breakers designed to handle the intense electrical arcs characteristic of Direct Current (DC) systems. Unlike standard miniature breakers (MCBs), these Molded Case units are built to withstand significantly higher fault currents and provide a physical point of isolation for heavy-duty power systems. They feature a high-strength, flame-retardant housing and a quick-trip mechanism that ensures faults are cleared in milliseconds to prevent catastrophic equipment failure or fire.

Applications

• Solar Battery Isolation: Installed between a 24V or 48V Lithium/Lead-Acid battery bank and an inverter to protect the battery from short circuits.

• PV String Protection: Used in commercial solar combiner boxes to protect large strings of solar panels before they enter the inverter.

• Industrial DC Networks: Ideal for protecting DC motors, telecommunication power hubs, and industrial automation control panels.

• Electric Vehicle (EV) Infrastructure: Employed in charging stations and heavy-duty DC distribution boards.
