Product Parameters

 

New exterior and structural design

A brand new exterior structural design, novel and unique, with good contact performance and large flow capacity, 
which is different from other ordinary products in the market. 
The maximum lightning protection capacity of a single module can reach (8/20us) 80kA, (10/350us) 12.5kA

 

A brand new color recognition system

A brand new color recognition system with a strip recognition system on the surface of the product, 
which can facilitate customers to quickly distinguish the types of various products,

Quality traceability system

Products can achieve visual tracking, and each product base is equipped with a QR code recognition system. 
By scanning with a mobile phone, the factory test data, model, date, batch, etc. of each product can be traced, 
strictly controlling the quality and consistency of each product.

 

Innovative thermal release circuit breaker technology

No external detachment device is required, and the detachment device can be installed with reliable interruption, 
achieving complete isolation and concealment after tripping, 
and self extinguishing of the arc, 
effectively avoiding the phenomenon of wire drawing

 

New hot Plug and drop design

Replacement can be carried out without interrupting system operation. 
Pressing the contacts on both sides of the module allows for easy insertion and removal. 
It has a foolproof design, self-locking function, and is easy to maintain

New arc insulation board design

We have installed arc insulation plates between each phase and between the wiring connections, effectively preventing the occurrence of arc pulling and flying between phases, greatly ensuring the stability and reliability of the product,

 

Remote recording function

Each product can add remote signaling terminals/intelligent monitoring modules as needed to measure and monitor the current/working status of each circuit, remotely record and display the operating status, and can be monitored through mobile phones or computers,

 

Multiple choices to meet different installation environments

Different combination methods can be selected according to different power distribution systems, 
with small product volume. Additionally, four wire products can be provided, 
which can be used as two two two wire products
