Rish Relay 252-Pxx - Mili-Volt / Thermo-couple Relay
The Protector trip accepts DC Millivolt inputs from transducers or shunts or from any standard thermocouple. The Relay offers user adjustable trip point ( Set point ) and time delay settings. The typically 0 to 10 seconds, although longer delays are available.

Product Function
‘Over’ Models: When the monitored voltage exceeds the setpoint, the time delay is started. When the time has elapsed, the relay will energize and the red LED will illuminate to indicate the trip condition. The relay will automatically reset once the monitored voltage falls below the setpoint minus the differential. When reset, the LED will extinguish, and the relay de-energises. The time delay is not active when resetting.
‘Under’ Models: When the monitored voltage falls below the setpoint, the time delay is started. When the time has elapsed, the relay will de-energize and the LED will extinguish to indicate the trip condition. The relay will automatically reset once the monitored voltage rises above the setpoint plus the differential. When reset, the LED will illuminate and the relay energizes. The time delay is not active when resetting.

Rish Relay - AR
Rish Relay - AR monitors AC current of a system/equipment and protects it from overcurrent, undercurrent and current unbalance. As well as it indicates the occurrence of faults with help of LED indications. It is a potentiometer based relay thus it is easy to programme trip points and time delays
Rish Relay 252-PAx - AC Current Relay
The AC Current provides continuous surveillance of the monitored circuit. When the measured current moves outside the set point limit, the relay will operate. An adjustable time delay is provided to prevent the relay from tripping for a predetermined period to prevent nuisance tripping.
