RN-101M Single phase over and under voltage relay with time delay

Description

16A 220V/50 HZ Single phase over & under voltage relay with time delay-RN-101M is designed to de-energy industrial/appliance single-phase 220V/50Hz load.

Features:

• protects the switched load against high-frequency and high –voltage impulse interference;
• load disconnection in case of a current overload (at the current higher than 16 A);
• indicates the circuit RMS voltage.

The device front panel features a load status indicator (on/off) and a three-digit, seven-segment display, which displays (depending on the device status):

• actual RMS voltage;
• the accurate value of the set-up parameter;
• time remaining till automatic load re-energizing;
• emergency de-energizing the load (RMS voltage flashing).

The variable pot knobs on the front panel allow for setting:

• the maximum allowable voltage tripping threshold;
• the minimum allowable voltage tripping threshold;
• time delay for load re-energizing after the circuit parameters recovery
