MONITORING RELAY CURRENT 1CO 8A 250VAC ADJ. 0.5-5A

The PRI-51 monitoring relay is used to monitor current levels in single-phase AC circuits. Stepwise adjustment of the current threshold enables its use in various applications. The output contact is open in normal condition. When the set current threshold is reached, the relay contact closes after the set delay (0.5-10s). Upon returning from fault condition to normal condition, the contact opens after exceeding the hysteresis (5%). Thanks to multi-voltage control, the relay can be used flexibly in different applications. The relay can monitor loads supplied by a source different from the PRI-51 relay's supply. Features
