The Midnite Solar Panel Mount Breaker MNEDC series is a family of high‑quality DC circuit breakers designed specifically for solar photovoltaic (PV) systems, battery systems, and other DC power architectures. They serve as critical over‑current protection and disconnect devices in solar installations — safeguarding equipment, wiring, and users from overloads, short circuits, and electrical faults in DC circuits.
These breakers are available in a range of ampere ratings — from 5 A, 15 A, 30 A, 100 A, up to large capacities like 175 A and 250 A — allowing system designers and installers to choose the right protection level for different segments of a solar system.
