Dold 3 Phase 4 Wire Undervoltage Relay

This Dold 3 Phase 4 wire undervoltage relay is an electrical switch designed to turn on or off the current within an electric circuit. An undervoltage relay operates when the voltage that is passing through the coil relay falls below a predetermined level.

Relays operate much like a light switch, power is switched on and off when the switch lever is moved, the primary difference is that a relay is operated by an electrical supply as opposed to being physically pressed. The DOLD 3 Phase 4 wire undervoltage relay protects loads against damaging voltage drops that could lead to power shortages and brown-outs. Applications include induction motor systems and other motorised industrial process applications.
