EARU DC Miniature Circuit Breaker EACBDC-63, 10A–63A, 1000V DC for Solar & Battery
EARU EACBDC-63 is a DC miniature circuit breaker built for high-voltage solar PV strings, battery banks and DC distribution. It protects cables, inverters and batteries from overload and short circuits up to 1000V DC.

Why use a DC MCB?
A short circuit or overload on a solar or battery line can burn cables, damage the inverter or the battery. A proper DC-rated breaker interrupts DC current safely — an AC breaker is not designed for this.
