Its compact size and DIN rail mounting enable easy installation, making it a top choice for professionals seeking reliable, high-quality circuit protection. ## Description Product description Chtaixi DC Miniature Circuit Breaker Warm Tips Pay attention to polarity. Select wire size according to rated current. Magnetic Arc Extinguishing AC has a zero-crossing point, but DC does not, so DC arc is more difficult to extinguish than AC arc, which is why AC circuit breakers can not be used for DC power, and DC circuit breakers can be used for AC power. This DC mini circuit breaker is equipped with a magnetic field system under the breaking contacts, which can pull the arc to the arc extinguishing chamber to assist arc extinguishing. Quality Products to Protect Your Electricity Safety Polarity Marked This DC MCB has no polarity requirement in use, and the positive and negative poles can be inverted. However, the installation, use, and maintenance of DC circuits are based on polarity requirements. So, in order to provide reliable indication and reference for the distribution, we highly recommend that you connect the wires according to the marked polarity. Tunnel Terminal The clamping design of the terminal block is designed to connect firmly, and the tightening torque is 2.5 N.m. ( Soft silicone wire needs to crimp fixed the wire end with copper crimp before wiring. ) Make sure that the wires are tightly connected when connecting to prevent loosening and heating. The surface of the terminal is tin-plated, and the plating layer can improve conductivity, corrosion resistance, and durability. Silver Alloy Contacts Contacts are very important to circuit breakers, especially for DC distribution with high arc extinguishing requirements. Good contacts can reduce the heat generated by arcing during disconnection and reduce the wear of the contacts. This DC circuit breaker uses silver alloy contacts, which improves electrical durability, and protects your electricity safety for a long time. Specifications Installation DIN Rail Install the 35mm DIN rail horizontally in a stable environment. Hang the circuit breaker slot on the DIN rail Push the lower end of the circuit breaker into the DIN rail Dismounting Push the circuit breaker upward Turn the upper end of the circuit breaker out of the DIN rail Review: Easy to install - We installed these to be a quick disconnect for our solar panels. It's doing It's job and was easy to install. Review: Very good - Very good—I recommend it. ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B096315TSJ | | Best Sellers Rank | #10,947 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #4 in Miniature Circuit Breakers | | Brand | CHTAIXI | | Brand Name | CHTAIXI | | Circuit Breaker Type | Standard | | Current Rating | 63 Amps | | Customer Reviews | 4.6 out of 5 stars 694 Reviews | | Item Dimensions D x W x H | 1.42"D x 2.95"W x 3.15"H | | Manufacturer | CHTAIXI | | Model | DZ47Z-63 | | Mounting Type | DIN Rail Mount | | Number Of Poles | 2 | | Number of Poles | 2 | | Part Number | 47Z63-2P1000 | | Product Dimensions | 1.42"D x 2.95"W x 3.15"H | | Smart Home Compatibility | Not Smart Home Compatible | | Unit Count | 1.0 Count | | Voltage | 1000 Volts | ## Product Details - **Brand:** CHTAIXI - **Circuit Breaker Type:** Standard - **Current Rating:** 63 Amps - **Mounting Type:** DIN Rail Mount - **Product Dimensions:** 1.42"D x 2.95"W x 3.15"H ## Images ![DC Miniature Circuit Breaker 1000V - Image 1](https://m.media-amazon.com/images/I/61wmqv80TRL.jpg) ![DC Miniature Circuit Breaker 1000V - Image 2](https://m.media-amazon.com/images/I/51vBlz4lZoS.jpg) ![DC Miniature Circuit Breaker 1000V - Image 3](https://m.media-amazon.com/images/I/519Po4aZA2L.jpg) ![DC Miniature Circuit Breaker 1000V - Image 4](https://m.media-amazon.com/images/I/61DJUH2YEHL.jpg) ![DC Miniature Circuit Breaker 1000V - Image 5](https://m.media-amazon.com/images/I/51j6DliopPL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Which side of the breaker is the input Source and which side is connected to the Load?** A: The way I understand thing - there is no input or output. You could connect your wires the way it suits you most. With that being said, some people will put the "input" wires on the bottom and the "output" ones on the top. At least, that's what I did. **Q: is there something wrong with putting 2 positive wires onto the product to use as shut off..while still having fuses in line?** A: No **Q: I would like a diagram of exactly how to wire this up. also, i see the seller mentioned a manual. can i request one also?** A: This breaker is as simple as it gets. As you look at the breaker there is a plus and minus indicators at the very top of the breaker. This is where your 12 volt supply connects. The 2 bottom terminals correspond directly to the 2 top terminals, positive on the right, negative on the left, top to bottom. These terminals on the bottom are what you connect the load you are protecting to, for example a solar charge controller or a solar array. The wiring schematic is located on the front of the breaker. I can't answer to the manual, I did not need one. You can go to You Tube and view a number of tutorials on these breakers. **Q: Are the terminals large enough to take a 1/0 awg cable?** A: The terminals are small for 1/0 but good for smaller wires from PV. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to install *by H***N on September 24, 2025* We installed these to be a quick disconnect for our solar panels.
