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.

Circuit Breaker Purchase Instructions

The cause of the circuit breaker fire
1. The current is high and the cable is thin, and the cable heats up and causes a fire
2. Poor contact, the screws of the circuit breaker are not tightened, causing the screw part of the circuit breaker to heat up and catch fire (90% of the fire causes)
Note: Be sure to tighten the screws -- important!!!
3. The quality of circuit breakers is poor. Our company selects A-level standard materials and flame-retardant shells for production. Each product is tested, and the quality pass rate reaches 99.5%.
4. Dust enters, humid environment; the circuit breaker is not waterproof and dustproof, try to use it in a waterproof box.
Note：If you find that the screw part of the circuit breaker is burned, 99% of it is because the screw is not tightened

How to choose the current of the circuit breaker
The current of the circuit breaker needs to be 20% larger than the working current. If the working current is 20A, Please choose 25A circuit breaker. If choose 20A, the circuit will trip and power off
