Product Details

（Ⅰ）Overview

The product integrates advanced low-voltage electrical equipment technology and digital intelligent communication technology to realize high switching life, low-power operation, remote switching, dual protection, metering, and other functions in small size.

 

（Ⅱ）Standards compliant

GB/T 14048.2，IEC60947-2

 

（Ⅲ）Scope of application

1. Power distribution of 4G/5G telecom system
2. Power management of low voltage DC application
3. Special field application

 

（Ⅳ）The main function

Protective function Protection features Describe
Undervoltage protection Self-recovery

At default settings, the breaker will disconnect the main circuit when its DC voltage is below - 40V for > 10s. When it returns to above - 42V, the breaker will automatically return to previous status.
Overvoltage protection Self-recovery

At default settings, when its voltage is above -85V, the breaker will disconnect the main voltage. When it returns to below -82V, the breaker will automatically return to previous status.

Over current

 Limited self-recovery

Overcurrent alarm and protection functions can be customized by customers;
Under the default setting:
Overcurrent alarm threshold  162A
Primary overcurrent protection threshold  162A
Primary overcurrent protection delay  5s

The secondary overcurrent protection function is related to the rated current:

More than 145%In for 2 seconds, the breaker will disconnect;

Alarm self-recovery：Self-recovery of electronic switch disconnection for primary and secondary overcurrent protection can be set, but it is not restored by default.
Short circuit protection No self-recovery No self-recovery by default
Over temperature protection Self-recovery Trigger protection when internal or terminal overheats

 

（V）Product Highlights

1. High breaking capacity: traditional product 6kA, KingSi's product 10kA.
2. Fast switching speed: traditional product 100ms, KingSi's product ≤20ms.
3. Ambient temperature: traditional product -25~65℃, KingSi's product -40~75℃.
4. Product functions: traditional product only have overload and short circuit protection, KingSi's product additional over and under voltage, over temperature, measurement, remote control function.
