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: They snap on or off great.no real complaints - 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 Review: Works as advertised - Have installed one to isolate my 50 amp dc to dc charger in my truck camper. Works as advertised but need more evaluation time. ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BFF6HG9V | | Best Sellers Rank | #27,633 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #12 in Miniature Circuit Breakers | | Brand Name | DIHOOL | | Circuit Breaker Type | Standard | | Current Rating | 100 Amps | | Customer Reviews | 4.6 4.6 out of 5 stars (129) | | Included Components | Circuit Breaker + DIN Rail | | Item Dimensions D x W x H | 2.95"D x 3.15"W x 2.95"H | | Item Weight | 0.36 Pounds | | Manufacturer | DIHOOL ELECTRIC | | Model | 6 | | Mounting Type | DIN Rail Mount | | Number of Poles | 1 | | Part Number | DZ47X-1P-100A | | Smart Home Compatibility | Not Smart Home Compatible | | Unit Count | 1.0 Count | | Voltage | 400 Volts | ## Product Details - **Brand:** DIHOOL - **Circuit Breaker Type:** Standard - **Current Rating:** 100 Amps - **Mounting Type:** DIN Rail Mount - **Product Dimensions:** 2.95"D x 3.15"W x 2.95"H ## Images ![DIHOOL AC/DC Miniature Circuit Breaker, Single Pole 100 Amp, 12V 24V 48V 400V, Non Polarized, Solar Disconnect Switch, DIN Rail Mount, RV Battery Isolator, PV Array MCB, Thermal Magnetic Trip - Image 1](https://m.media-amazon.com/images/I/61s7irTjqkL.jpg) ![DIHOOL AC/DC Miniature Circuit Breaker, Single Pole 100 Amp, 12V 24V 48V 400V, Non Polarized, Solar Disconnect Switch, DIN Rail Mount, RV Battery Isolator, PV Array MCB, Thermal Magnetic Trip - Image 2](https://m.media-amazon.com/images/I/61clUpkzU8L.jpg) ![DIHOOL AC/DC Miniature Circuit Breaker, Single Pole 100 Amp, 12V 24V 48V 400V, Non Polarized, Solar Disconnect Switch, DIN Rail Mount, RV Battery Isolator, PV Array MCB, Thermal Magnetic Trip - Image 3](https://m.media-amazon.com/images/I/51uVtVt8aCL.jpg) ![DIHOOL AC/DC Miniature Circuit Breaker, Single Pole 100 Amp, 12V 24V 48V 400V, Non Polarized, Solar Disconnect Switch, DIN Rail Mount, RV Battery Isolator, PV Array MCB, Thermal Magnetic Trip - Image 4](https://m.media-amazon.com/images/I/61KiVYOKtTL.jpg) ![DIHOOL AC/DC Miniature Circuit Breaker, Single Pole 100 Amp, 12V 24V 48V 400V, Non Polarized, Solar Disconnect Switch, DIN Rail Mount, RV Battery Isolator, PV Array MCB, Thermal Magnetic Trip - Image 5](https://m.media-amazon.com/images/I/51gub+vZuZL.jpg) ## Available Options This product comes in different **Lens Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ They snap on or off great.no real complaints *by R***K on March 19, 2026* Breaker works perfect.
