Product Overview

JRQ industrial control relay is a high-power electromagnetic relay, which uses weak current signals to control high-power circuits and realize circuit switching. It has 30A switching capacity and adopts open dust-proof structure. Featuring stable electrical parameters and strong load capacity, it is widely used for load and power switching in electronic control systems of automation equipment, power facilities and new energy devices.

Product Features

① It supports 30A AC/DC switching; AgCdO contacts resist arc erosion.

② Fast response: operate time 20ms, release time 15ms, contact resistance ≤100mΩ.

③ Excellent dielectric strength and vibration resistance for continuous cyclic operation.

Working Principle

① Coil energization generates electromagnetic force to close contacts.

② After power-off, reset spring opens contacts automatically.

③ It separates weak-current control circuit and high-power load circuit, compatible with PLC control.

Materials & Structure

① Contacts: AgCdO alloy with good conductivity and arc resistance.

② Terminals: high-conductivity copper; flame-retardant plastic housing.

③ Open dust-proof structure; 1C and 2C contact configurations optional.
