HL-10.20.30 series static current relayDetailed product description：

1. Overview

The HL series integrated circuit current relay is used as a starting element in overload short-circuit protection devices for motors, transformers, and transmission lines. This product is an integrated circuit static relay with high precision, low power consumption, short action time, high return coefficient, intuitive and convenient setting. It overcomes the shortcomings of electromagnetic relays such as easy contact shaking, high working noise, difficult adjustment of action return coefficient, and variable action value after transportation. The product is divided into three series
Column: HL-10, HL-20, HL-30, can replace DL-10, 20, 30, JL-10, 20, 30 respectively
