Zelio™ Current Measurement Relays
Zelio Current Measurement Relays are designed to measure under and overcurrent conditions, without external sensors. Current measurement relays enable continuous monitoring of the operation of electrical and mechanical loads such as motors and heaters. They are DIN rail mountable and the control status is indicated by an LED. RM17JC Current Control Relay • Monitors AC currents
RM35JA Current Control Relays • Selection between overcurrent or undercurrent • Automatic DC or AC recognition • Selectable memory function
• Designed to monitor overcurrent • Equipped with an integrated current transfmormer
