PRI-51/2 | RO/SE

Current monitoring relay, PRI-51/2, RO/SE

Monitoring relay PRI-51/2 is used for current level monitoring in 1-phase AC circuits. The stepped The stepped adjustment of the required current opens up many different application possibilities. The output relay is switched off in the normal state. When the set current level is exceeded, the relay is switched on after the set delay (0.5-10s). When resetting from fault to normal state, there is a hysteresis (5%). The advantage of this relay is UNI voltage. It is possible to monitor a load that does not have the same supply as the PRI-51/2 monitoring relay. The range of the PRI-51/2 can be increased by an external current transformer.
