Current monitoring relay EMR4-I [t-head2]

The current monitoring relay EMR4-I is suitable for the monitoring of AC as well as DC current. Pumps and drill machines can be monitored for low load or overload. That is due to the selectable under or over limit.
There are two versions each with three measuring ranges (30/100/1000 mA, 1.5/5/15 A). The multi-voltage coil allows universal use of the relay. The two auxiliary changeover contacts allow for a direct feedback.

Selected bridging of short current peaks [t-head3]

By using the selected time delay of between 0.05 and 30 s short current peaks can be bridged.
