MultiTek AC Current Relay

M200-A1U Single phase under current
M200-A1O Single phase over current
M200-A1C Single Phase combined current
M200-A3U 3 Phase under current
M200-A3O 3 Phase over current

The M200 AC current relays provide current monitoring and protection in both single and 3 phase systems. Used in applications such as motor protection, load detection and generator control.
Under over and combined under/over units are available. The relay operates when the adjustable trip point is reached. An externally adjustable time delay is provided to prevent nuisance tripping.
As is common with all the M200 relays, on over units the relay energises when the input signal exceeds the trip point On under units the relay de-energises when the input signal goes below the trip point.
A red LED indicates the state of the relay, whilst a green LED indicates the condition of the power supply.
