Function: High quality AC mini circuit used for line overload, short circuit protection and infrequent conversion of lines. It can also work as on-off switch for load circuits.

This is a great circuit breaker used to protect a low-voltage DC electrical system from damage caused by excess current resulting from an overload or short circuit

Fast trip to ensure reliable operation of the load and prolong the life of electrical circuit breakers. It can also work as on-off switch for DC load circuits

DC breaker is more powerful than AC breaker to extinguish arcs. It means that our low-voltage breaker can be used at the same level voltage of DC and AC circuit system

[GREAT QUALITY]: Made of high quality plastic(ABS), Waterproof Rating: IP65; Qualification£ºCE¡ROHS

[Designed]: This distribution box is designed for 5 ways circuit breaker,durable and sturdy.

[TRANSPARENT COVER]: The blue cover is transparent , you can check the condition easily without open the box.

【High Quality】 - Our DC circuit breaker ensures reliable operation of the load and prolongs the life of DC circuit breakers. It can also work as an on-off switch for DC load circuits. Positive and negative pole wires can be reversed without any risk, making it a safe and convenient choice for your needs.

【Easy To Use】 - Our DC circuit breakers are designed to be more precise trips based on current, even in extreme temperatures ranging from -40ºC to 85ºC, without re-rating. The color indicators in the handle make it easy to see the operational status at-a-glance, so you can use it with ease.

【Wide Applications】 - Our DC circuit breaker is simple and reliable to use, supporting short circuit protection and overload protection. It is widely used for solar panels grid systems, wind and solar hybrid systems, and many other DC systems, making it a versatile choice for your needs.
