The function for breaking faulty current above the setting value
within the shortest time to protect the circuit from short-circuit.
1. Standard current setting Knob-Ii
�Setting range : 2/3/4/6/8/10/12/15/Off to In
2. Relay operates basing on the largest load current
among R/S/T/N Phase.
3. Total breaking time is below 50ms
4. Relay operating current can be adjustable by Fine
Adjustment
1. Instantaneous
