Description

Overview

This is a multi-functional intelligent circuit breaker. The product integrates power electronic semiconductor technology, low-voltage electrical equipment technology and digital intelligent communication technology to realize low-power operation, remote switching, dual protection, metering and other functions in small size. The product has mechanical breakpoint, which meets the requirements of electrical insulation and isolation.

Application Scope

  •  Load side power distribution of 4G/5G telecom system

  • Power management of low voltage DC application

  • Special field application

Protection features

Description

Under voltage

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.

Over voltage

Limited self-recovery  

At default settings, when its voltage is above -63V for >10s, the breaker will disconnect the main voltage. When it returns to below - 60V, the breaker will automatically return to previous status. When its voltage is above -66V, the breaker will totally disconnect the main voltage and could not self-recover.

Overload

limited self-recovery

Overcurrent alarm and protection functions can be customized by customers;
Under the default setting:
Overcurrent alarm threshold  66.15A
Primary overcurrent protection threshold  69.3A
Primary overcurrent protection delay  120s

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

More than 130%In for 0.2 seconds, the electronic switch will disconnect.

Short circuit

limited self-recovery

Try self-recovery every few milliseconds and stop self-recovery if failed for 3 times within 30s.

Over temperature

Self-recovery

Triggered by overheat of inside or terminal, electronic switch off.
