Fast Arc Extinguishing Capability
Automotive circuit breakers, marine circuit breakers, fuses and other products do not have the ability to extinguish arcs. The higher the voltage, the larger the arc generated when on and off, and the easier it is to cause equipment to burn. Our circuit breakers have the ability to extinguish arcs, making it safe to switch on and off.
Fire Retardant Enclosure
It is very important to use flame-retardant enclosures for electrical equipment. If inexpensive non-flame-retardant enclosures are used, fires are likely to occur.
Our DC circuit breakers feature high quality flame retardant housings
Thermal Magnetic Trip
When the circuit current exceeds the rated current of the circuit breaker, the circuit breaker will heat up and disconnect. The greater the current, the shorter the disconnection time.
The circuit breaker with thermal magnetic tripping characteristics will not trip instantaneously between 1-3 times the current
How to Install to the DIN Rail
Install
- Snap the front bottom of the circuit breaker into the DIN Rail
- Press down on the circuit breaker to engage the front clip
Unload
- Push the circuit breaker forward and upward to remove the circuit breaker
Phillips Screwdriver Wiring
- 3N.m Torque Screw Torque
- Be sure to use a screwdriver to tighten the copper wire to avoid poor contact, heat and fire
- Recommend use terminals for wiring, more safty
Safer With Circuit Breaker Box
- Use circuit breaker box, IP65 dustproof and waterproof, more safty
- Prevent electric shock, more safty
- With transparent window
- Easy to open and close circuit breaker
- Freely placed or screwed

I used these for my solar combiner box. Six strings, six breakers. Internet has mixed feelings about using this style but I haven't had any issues.

Only plus was that this breaker included the DIN rail mounting hardware and ferrules for the wire. Even with ferrules on the wire ends the terminals had difficulty holding the wire. I had to resort to Over-tightening the terminals just to keep the wire from pulling out. Also while tightening the terminals, even before reaching high torque, the enclosure of the breaker started separating at the seam. I will give it credit for the strength of the terminal lugs, because those puppies are tight now, lol.

I'm using these for Solar Panel / Inverter setups. All the way up to # 1 awg wire. Love 'em.

These appear to be quite nice ac/dc breakers. I like that the vendor has the foresight to include a bit of DIN rail if you need it. The price was reasonable and the delivery was quite quick as I did not have to wait for shipping from China. I would purchase these again.
