Review: Works good - Works good with my solar system
Review: Good product for a good price. - Product is well manafactured. A good value for the money. Installed it no problems.

## Features

- FUNCTIONS: Used to protect 48~500VDC OR 90~480VAC circuit from overload and short circuit damage and 12~48VDC from overload damage, and can also be used for control and isolation. Size: 54MM x 80MM x 75MM, Fit for 35mm DIN rail.
- Breaker Switch has built-in arc squelching magnet which enables the high arc extinguisher,flame-retardant enclosure, silver alloy contacts, and sufficient pure copper coils to ensure its high quality.
- Come with 1 x DIN rail, 2 x screws for easy mounting and 4 x copper crimp terminal for wiring to make sure that the wires are tightly connected.
- This Solar Disconnect Switch is suitable for photovoltaic solar panel array,Solar Charge Controller,Batteries,Power inverter,DC motor protect and also suitable for ac systems, RV, home circuits, or other 50/60Hz AC systems.
- FAST TRIP: The electromagnetic trip system can trip immediately when the circuit is short-circuited to protect the safety of the circuit.
- Non-polarized circuit breakers do not require polarity distinction and can be connected in either direction, simplifying installation and reducing wiring errors. They are particularly suitable for applications where polarity may reverse, such as:Reversible motors,Battery charge/discharge switching,Bidirectional current protection including:EV charging/discharging circuits,Solar power systems (where battery current direction reverses),Industrial reversible drive systems.
