（Ⅴ）The main function

Protection functionProtection featuresDescription
Under voltageSelf-recoveryAt 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 voltageLimited 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.
Overloadlimited 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 circuitlimited self-recoveryTry self-recovery every few milliseconds and stop self-recovery if failed for 3 times within 30s.
Over temperatureSelf-recoveryTriggered by overheat of inside or terminal, electronic switch off.
