SUNTREE MCB 32A 2P DC MCB 32A 2P DC

A SUNTREE MCB 32A 2P DC (32 Amp, 2-Pole DC Miniature Circuit Breaker) is used to protect DC electrical circuits, especially in solar photovoltaic (PV) systems and battery storage systems. It disconnects the circuit automatically if there is an overload or a short circuit, preventing damage to cables, inverters, batteries, and other equipment.

Main uses:

Protects solar PV strings between the solar panels and the inverter.

Protects battery cables in DC battery systems.

Trips automatically if current exceeds 32A or a short circuit occurs.

2-Pole (2P) design disconnects both the positive (+) and negative (−) DC conductors at the same time for improved safety.


It is commonly installed in:

Solar combiner boxes

DC distribution boards

Hybrid inverter systems

Off-grid and battery energy storage systems
