Single phase Load Shedding Relay

Product catalog summary

Overview
The Single Phase Load Shedding Relay is designed to manage power consumption by disconnecting non-priority circuits during peak usage to prevent tripping the main circuit breaker. It measures the total current using a toroidal transformer and displays it. An internal buzzer alerts users when consumption exceeds the set maximum current.

Operation
When the current exceeds 10% of the maximum set current, the relay disconnects non-priority loads to maintain consumption at an acceptable level. These loads are reconnected after a pre-adjusted restart time.

Single phase Load Shedding Relay. The load shedding relay limits the power consumption before tripping the main circuit-breaker . T do this, non-priority circuits will be disconnected during peaks of power consumption. o The total current of the installation is measured by a small toroidal transformer and shown on the display. When it reaches the maximum current set, an internal buzzer alerts of over-consumption. If measured current exceeds 10% of maximum current, the non-priority load is disconnected to keep consumption at admissible level. The non-priority load is re-connected after a re-start...
