The current is measured through an external shunt. 1-phase and 3-phase current up to 500 AAC can be monitored connecting MI or MP current transformers. Housing Function Type Item number Output Power supply Range Owing to the built-in latch function, the ON-position of the relay output can be maintained. Inhibit function can be used to avoid relay operation when not desired (maintenance, transitions). The LED's indicate the state of the alarm and the output relay.

When connected with MI or MP current transformer (using the 0.4 to 4 Vp range) they can monitor 1-phase or 3-phase AC current up to 500 A. Example 1 (connection between terminals Z1, Y1 or 8, 9 - latching function enabled) The relay operates and latches in operating position when the measured value 2 exceeds (or drops below) the set level for more than the set delay time. Provided that the current has dropped below (or has exceeded) the set point (see hysteresis setting), the relay releases when the interconnection between terminals Z1, Y1 or 8, 9 is interrupted or the power supply is interrupted as well. The red LED flashes until the delay time has expired or the measured value comes back to a non-alarm value (see hysteresis setting). Example 2 (MI CT) (no connection between terminals Z1, Y1 or 8, 9 - latch function disabled) The relay operates when the current flowing in the CT exceeds (or drops below) the set level for more than the set delay time. It releases when the current drops below (or exceeds) the set level (see hysteresis setting) or when power supply is interrupted. Example 3 (MP CT) (no connection between terminals Z1, Y1 or 8, 9 - latch function disabled - over cur- rent measurement) The relay operates when the maximum current flowing in the CT exceeds the set level for more than the set delay time. It releases when the maximum current drops below the set level (see hysteresis setting) or when power supply is interrupted. Note When the inhibit contact is opened, if the input signal is already in alarm position, the delay time needs to elapse before relay activation.
