JGL series two phase reverse time overcurrent relay

Main Technical Parameters

Setting range: 2-20 (220V auxiliary power supply)
Rated current: 5A (10A) 
Quick break delay: 0-0.9S 
Timing limit delay time setting range: 0.5-99.9S, differential is 0.1S; Setting error 0.1%,Setting value is + 10ms 
Inverse time delay time setting range: 0.5-99.9S, difference is 0.1S; (the delay time tuning value of the reverse time delay time is 2 times the action current) 
Speed current multiple setting range: 2-10 times
The fast break delay is set at 0 seconds. The delay error is not more than 1% and setting value is 10ms when the operation time (Relay inherent action time) is not more than 50ms and the whole time is 0.1-0.9S.

Overcurrent action setting

1.The first group of three digital switches on the relay panel are 10 digits from left to right, with single digits and red characters representing decimal numbers. The digital switch is set at 020, that is, the overcurrent setting value is 2A.

2. The second group of switches on the panel consists of two numbers, from left to right are 10 digits and single digits respectively. The switch setting number is a quick break multiple, the quick break current setting value = the overcurrent setting value * the quick break multiple, for example, the overcurrent setting value is 2A, If the quick break multiple is 6 times, the fast breaking current=2*6=12A

Overcurrent reverse time setting

First of all, the overcurrent delay switch is hit on the reverse time limit side. For the convenience of setting, the time of setting the time delay is 2 times the action current.

For example, when the delay time relay is 3.5 s at 2 times current, the time switch 035 can be directly set from the table to find out that the reverse time delay time of 10 times current is 0.5s (attached: the relation table between current multiple and inverse time delay time)
