MidNite's MNSPD-300-AC is a surge protection device designed to protect AC solar PV components from electrical surges like lightning strikes. Rated for indoor or outdoor use, it can provide protection to service panels, load centers, or any electronic device requiring protection.
The surge protector works by clamping current surges to a safe voltage that will not damage the electronics in the circuit in which it is installed. Blue LEDs visible from a distance indicate that the device is working properly and your system is protected from power surges.
This 300-volt AC model is ideal for 120/240VAC circuits.
