## Description

Product Specifications Model: DZ47X 1P 100A Rated Operating Voltage : DC 12V-500V And AC 90-480V Poles: 1P Rated Current: 100A breaking capacity: 4 kA Ics=Icu Trip Curve: B Mechanical Life: 10,000 times Electrical Life: 4,000 times Installation Method: 35MM DIN Rail Standard: IEC60898 / GB10936 Operating Temperature: -30°C to +70°C Operating Altitude: 2000 Meter 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 ——————————————————————

Review: Good - Got these breakers from a video I saw on YouTube to connect my 48 volt Server battery to my power station. While the battery already has its own breaker switch I decided to use this AC/DC switch as a secondary precaution. Also when using a breaker switch for a power station setup you want to make sure the switch is properly rated for DC or AC and that it is designed to handle power going both directions whether it is charging or providing power so that way at the breaker can trip properly if the current exceeds the limitations. Haven't tested the surge protection but to connect the wires was very easy with the adjustable terminal clamps the provided rail allowed me to use both breakers for my setup so that was nice
Review: Great option for solar panel disconnect - A durable and easy to mount circuit breaker, works well as a solar panel disconnect, great value and

## 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.

### ⭐⭐⭐⭐⭐ They snap on or off great.no real complaints
*by R***K on March 19, 2026*

Breaker works perfect. Just wish there was a way to make them both turn on or off at the exact same time like some kinda little bar that goes across them both so they both turn on or off at exact same time otherwise perfect dc breakers.very happy with them
