Review: This breaker works well, but I found that the terminals did not have enough grip. Be sure to tighten the screws quite tight.
Review: I have 4 of these breakers (varying amps) incorporated into my solar setup in ny camper. They work well for disconnecting solar panels from charge controllers etc. I have load tested 3 of the 4 I have in use and found they broke circuit within 5-12% of the rated amps. They work well for me

## Features

- FUNCTIONS: Used to protect power distribution facilities from overload and short-circuit damage, and can also be used for control and isolation.
- FAST TRIP: The electromagnetic trip system can trip immediately when the circuit is short-circuited to protect the safety of the circuit.
- ARC EXTINGUISHING: DC arc extinguishing is more difficult than AC. This DC mini circuit breaker has a magnetic system to assist arc extinguishing.
- APPLICATION: Used in DC power system, ship electric power system, solar photovoltaic system, or other DC system.
- INSTALLATION: Screw clamp wires, 35mm DIN rail mount.
