Product Description


In the context of energy storage systems, the technical advantages of China Suppliers ICHYTI Non polarity DC circuit breaker (with no distinction between positive and negative poles for incoming and outgoing lines) are fully demonstrated.

This design breaks the polarity limitation of traditional DC circuit breakers. When there is a bidirectional current fault in the energy storage system (such as abnormal switching of battery charging and discharging states), it can achieve indiscriminate and fast disconnection, avoiding the problem of arc extinguishing failure caused by polarity connection, and greatly improving the reliability and installation convenience of the system operation.

CHYT Non polarity DC circuit breaker Feature

 Optimize the contact opening distance: By accurately adjusting the distance between the moving and stationary contacts, the jumping distance of the DC arc is shortened, and the energy threshold for arc formation is physically reduced;

 Add an arc ignition coil: Construct an arc guidance mechanism using the principle of electromagnetic induction, so that the arc can be quickly guided to the arc extinguishing chamber regardless of whether the current flows in the forward or reverse direction;

 Gradual cutting of arc extinguishing grid: The grid array in the arc extinguishing chamber forcibly decomposes the introduced arc into multiple short arcs, and quickly cuts off the fault current through heat dissipation and ionization effects.

When it comes to manufacturing, CHYT having the right production equipment is essential. Not only can the right equipment improve efficiency and output quality, but it can also provide a competitive edge for businesses. Let's take a closer look at the advantages of having the right production equipment.

First and foremost, having the right equipment can significantly improve production efficiency. With the latest technology, machinery can perform tasks far faster and more accurately than manual labor ever could. This translates to quicker production times and lower labor costs, resulting in a higher profit margin.

Moreover, production equipment can improve output quality. High-quality machinery can precisely measure, mix, and assemble materials, which results in products with more consistent quality. This leads to less waste, rejects, and rework, saving time and money in the long run.
