HSL-10 series static timed overcurrent relayDetailed product description：

1. Application scope
The HSL series static inverse time overcurrent relay is applied in the relay protection circuit of motor transformers and other equipment, as well as transmission and distribution systems. It is suitable for plants without DC equipment. When the main equipment or transmission and distribution system experiences overload and short circuit faults, the relay can reliably operate within the predetermined time limit, cut off the faulty part, and meet the requirements of the power department's compression time difference countermeasures.
The HSL series can replace GL-11, 21, 12, 22, 13, 23, 14, 24
15. 25, 16, 26 overcurrent relays can also replace DL-10, DL-
20, DL-30 series current relay.

2. Main technical parameters
Overcurrent setting range: 2-9.9A, with a step difference of 0.1A.
Quick break current multiple: 2-8 times.
Delay time setting range: 0.1-9.99S, with a difference of 0.1S.
Contact capacity: AC250V, can be connected to 5A for a long time, and the closing contact can break the current AC ≤ 2j
Power consumption: When the current is at the rated value, the power consumption of the relay is not more than 5W.

Setting method
There are three sets of digital switches on the relay panel, from left to right, which are the overcurrent action value, current quick break multiple, and overcurrent action time value. For example, if the overcurrent setting value is 7.5A and the quick disconnect digital switch is set to "3", the quick disconnect setting value is 22.5A, the maximum overcurrent action time is 9.99s, and the step difference is 0.01S.
