Qualities is good value for the money and it fits easily install installed easy install installation and protection level is great. Review: The product works well - This product works great. Please ensure you are using ferrules to crimp the end of the copper stranded wires before making the connection, or crip tight with a copper tube end, this will in most case prevent overheating and allow for better flow current. Also if you are using a inverter with built in charge controller is best to use a non polorized switch. This breaker is performs best in my opinion where the battery , inverter and solar controller are seperate devices. ## Features - FUNCTIONS: Used to protect power distribution facilities from overload and short-circuit damage, and can also be used for control and isolation. - ARC EXTINGUISHING: This DC circuit breaker has a magnetic system to assist arc extinguishing. - QUALITY: Silver alloy contacts, flame retardant material shell, color indicator. - APPLICATION: Used in solar photovoltaic system, or other DC system. - INSTALLATION: 35mm DIN rail mount, screw clamp wires(Soft silicone wire needs to crimp fixed the wire end with copper crimp first). ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B1WDKJNM | | Best Sellers Rank | #34,443 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #20 in Miniature Circuit Breakers | | Brand Name | CHTAIXI | | Circuit Breaker Type | Standard | | Current Rating | 125 Amps | | Customer Reviews | 4.6 4.6 out of 5 stars (124) | | Manufacturer | CHTAIXI | | Model | 2 Pole | | Mounting Type | DIN Rail Mount | | Number of Poles | 2 | | Part Number | 47NZ125-C | | Smart Home Compatibility | Not Smart Home Compatible | | Unit Count | 1.0 Count | | Voltage | 500 Volts | ## Product Details - **Brand:** CHTAIXI - **Circuit Breaker Type:** Standard - **Current Rating:** 125 Amps - **Mounting Type:** DIN Rail Mount - **Number Of Poles:** 2 ## Images ![DC Miniature Circuit Breaker 500V - Image 1](https://m.media-amazon.com/images/I/61rqk0QpPrL.jpg) ## Available Options This product comes in different **Part Number, Model, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good emergency switch *by G***M on October 17, 2025* The use is good.
