Featuring a thermal magnetic trip mechanism and magnetic arc extinguishing, it provides fast, reliable protection against overloads and short circuits. Its compact DIN rail mount design ensures easy integration into power distribution setups, making it an essential safeguard for modern DC power systems. ## 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: Works as it should - Working as it should. Review: Not very good set screw - The product itself is fine. The screw terminals won't tighten around the wires. Using 8 guage stranded wire. The terminals don't want to stay tight. ## 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 | B095YFQWHK | | Best Sellers Rank | #98,002 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #62 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 94 Reviews | | Item Dimensions D x W x H | 2.95"D x 1.42"W x 3.15"H | | Item Weight | 6.35 Ounces | | Manufacturer | CHTAIXI | | Model | DZ47Z-63 | | Mounting Type | DIN Rail Mount | | Number Of Poles | 2 | | Number of Poles | 2 | | Part Number | 47Z63-2P500 | | Product Dimensions | 2.95"D x 1.42"W x 3.15"H | | Voltage | 500 Volts | ## Product Details - **Brand:** CHTAIXI - **Circuit Breaker Type:** Standard - **Current Rating:** 63 Amps - **Mounting Type:** DIN Rail Mount - **Product Dimensions:** 2.95"D x 1.42"W x 3.15"H ## Images ![DC Miniature Circuit Breaker, 2 Pole 500V 63 Amp Isolator for Solar PV System, Thermal Magnetic Trip, DIN Rail Mount, Chtaixi DC Disconnect Switch C63 - Image 1](https://m.media-amazon.com/images/I/61l9mX+JsPL.jpg) ![DC Miniature Circuit Breaker, 2 Pole 500V 63 Amp Isolator for Solar PV System, Thermal Magnetic Trip, DIN Rail Mount, Chtaixi DC Disconnect Switch C63 - Image 2](https://m.media-amazon.com/images/I/51vBlz4lZoS.jpg) ![DC Miniature Circuit Breaker, 2 Pole 500V 63 Amp Isolator for Solar PV System, Thermal Magnetic Trip, DIN Rail Mount, Chtaixi DC Disconnect Switch C63 - Image 3](https://m.media-amazon.com/images/I/51qJuGBLh5L.jpg) ![DC Miniature Circuit Breaker, 2 Pole 500V 63 Amp Isolator for Solar PV System, Thermal Magnetic Trip, DIN Rail Mount, Chtaixi DC Disconnect Switch C63 - Image 4](https://m.media-amazon.com/images/I/61z3krj-uVL.jpg) ![DC Miniature Circuit Breaker, 2 Pole 500V 63 Amp Isolator for Solar PV System, Thermal Magnetic Trip, DIN Rail Mount, Chtaixi DC Disconnect Switch C63 - Image 5](https://m.media-amazon.com/images/I/51c7EdhDoqL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as it should *by T***I on August 8, 2025* Working as it should. ### ⭐⭐⭐⭐ Not very good set screw *by S***4 on June 2, 2022* The product itself is fine.
