Digital Contactor and Overload Relays PRODUCTS


Digital overload relay monitors the current values and these relays are used for protecting the engines from high currents. These are mostly used in devices that operate at sensitive current levels. The relays continuously monitor the input current to the device and activate if the load is higher than the set value. The contact is closed and prevents any damage or failure on the equipment.

When we consider the operating principle, we can see that the digital overload relays do not provide protection on their own. You need to use equipment to cut the circuit in case of a overload relay alarm. This equipment is either fuse or contactor.

There are models that contain digital contactors and overload relays together. Also, the Tense Electronics product family includes a built-in current transformer, external current transformer overload relays and digital contactor only models.
