Description

The Multifunctional Current Monitoring Relay is designed for over- or undercurrent monitoring. It uses a RMS measuring principle to accurately measure DC and AC currents. The relay has 3 measuring ranges: 3-30 mA, 10-100 mA, and 0.1-1 A. It operates with a rated control supply voltage of 24 - 240 V AC / DC. This relay features 2 CO (SPDT) outputs with contacts rated at 250 V / 4 A. It offers the option to select over- or undercurrent monitoring, as well as open- or closed-circuit operating principles. Additionally, it can be used with or without a latching function. The tripping delay and start-up delay of the relay are adjustable within a range of instantaneous to 30 seconds (0, 0.1-30 s). It also has double-chamber cage connection terminals for secure and reliable connections.
