About this item

  • 【Specification】Polos: 1P, Voltage: DC 250V, Current: 6A, Breaking Capacity up to 6KA, Breaking Time ≤ 0.03 S. ***Tip:The circuit breaker makes a strange noise when it shakes because we have added an arc extinguishing cover, which is not fixed inside. Therefore, the shaking causes the noise, and this is a normal situation
  • 【Strong Protection Features】The circuit breaker effectively protects 250V DC circuits from overload and short circuit damage. When the current exceeds 5 times the rated value, the circuit breaker will trip after 8 seconds; when the current exceeds 10 times the rated value, the circuit breaker will trip immediately, preventing damage to electrical appliances. The trip time is only 0.03 seconds, ensuring circuit safety and reliability
  • 【High-Quality Materials】 Made with high-precision molds, high closure accuracy; full copper contact pieces with conductivity 10 times higher than pure brass. The switch can handle up to 6000 on-off cycles, which is twice that of older models
  • 【Detail Improvements】Larger screw heads for easier and safer wire connections, 12 built-in arc extinguishing plates, 3 more than older models, effectively preventing flashover and arc, stronger outer shell, ensuring stability and preventing disassembly during tripping
  • 【Key Selling Points】Supports screw or terminal block connection with a high breaking capacity of 6KA, unique heat dissipation system for stable operation over long periods, new latch design for easier operation. The scene display design allows for easy identification
  • 【Unique Display Column Design】An additional display area allows you to attach scene stickers for easy identification of the room or area controlled by each circuit breaker, avoiding problems caused by incorrect switching
  • 【Applications】Undergone three safety tests and certified to meet all safety standards, we always prioritize customer safety. Wildly used in Photovoltaic Systems, Charging Stations, Battery, Power Distribution Systems

While I do not have a test setup to fully test the properties of this breaker. It does look good and does seem to trip properly.

I am using this as a circuit breaker/switch in a small solar system. Though as others have noted, it’s not UL listed, it appears to be well built and durable and was easy to install with the screw down wire clamp terminals. The breaker seems to be working so far, though it’s tough to actually test its protection capabilities until something goes wrong.

Review of DC 1 Pole Miniature Circuit Breaker, 250V 25Amps, C25I recently purchased the DC 1 Pole Miniature Circuit Breaker (MCB), rated at 250V and 25Amps, for my solar PV system, and I have to say, it’s been a solid addition to my setup. Here’s a detailed overview of my experience with this thermal magnetic trip MCB:Installation:One of the standout features of this circuit breaker is how easy it was to install. The design is intuitive, and I found the markings clear and easy to follow. It integrated seamlessly with my system, allowing me to set it up without any hassles. For anyone who might be intimidated by electrical installations, I can confidently say that with a bit of caution, you should have no issues.Performance:So far, the MCB is working as intended. The thermal magnetic trip function seems to operate effectively, responding promptly to any overloads, which is crucial for safeguarding my solar equipment. The 6KA breaking capacity provides a good safety margin, reassuring me that it can handle potential faults without compromising system integrity.Price Point:For the quality and features offered, the pricing is very competitive. I compared it to similar products on the market, and this MCB not only comes at a good price but also doesn’t skimp on reliability. It's impressive to find such a dependable product without breaking the bank.Durability and Build Quality:While I’ve only had it installed for a short period, the build quality appears robust. The materials used inspire confidence in its durability, which is especially important for outdoor applications like solar installations. I expect this breaker to withstand various environmental conditions, given its designed purpose.Conclusion:Overall, I’m quite pleased with the DC 1 Pole Miniature Circuit Breaker. It ticks all the boxes for ease of installation, performance, and affordability. If you’re looking for a reliable and cost-effective circuit breaker for your solar PV system, I would highly recommend considering this model. It seems to deliver exactly what it promises, providing peace of mind while ensuring the safety and efficacy of my renewable energy setup.

Works well in so far as I can test it. It operates as a switch well. It trips when connecting an inverter due to the inrush current but stays on after a reset. I am unable to measure that inrush but expect it well exceeds the 20A rating.

The MOLLOM breaker looks like it will do the job as a breaker or disconnect. I didn't test it to load, but it did trip with a short circuit. This isn't a UL item, so you won't be using this in a household or commercial setting, but it's good for an off-grid application, RV, or other setup that doesn't connect to the US grid.

Seems well made and the breaker switch has a smooth operation. DC rated so I can use it on my solar install.

Standard DC breaker for a DIN panel. Seems like fairly standard build quality, though the latches are not quite as nice as some of the other breakers that have been installed. Not the type of product where you can really tell the actual quality until something goes wrong. You really hope you never have to discover a key piece of electrical safety equipment is subpar. From the outside “touchy parts” it feels very much like any other DC breaker I’ve had my hands on.Let’s hope it works as advertised.Fair price for a standard DC breaker.
