Voltage Relay

Voltage monitoring relay il 5881 series dpdt 3 a din rail 230 vac screw check stock lead times.

Voltage relay. No separate supply input voltage is required on any macromatic voltage monitor relay since each unit is powered by monitored voltage. 2 in stock for next day delivery liege stock. Voltage sensing relays monitor either ac single phase 50 60hz or dc voltages to protect equipment against voltage fault conditions. Uk stock order before 18 00 mon fri excluding national holidays 1 more will be available on 12 10 20 more stock available week.

These relays switch through a series of different circuit configurations every time they receive an input voltage. This signal can be used to trigger an alarm or shut down sensitive equipment in an orderly manner to prevent permanent damage. Voltage monitoring relay ba 9043 series dpdt 3 a din rail 230 vac screw check stock lead times. Dc voltage monitoring relay with 2 c o contacts 2 form c or dpdt provide protection for the equipment from undervoltage and overvoltage in dc circuit 12v 24v 36v or 48v adjustable trip delay time led indicator for working state din rail mounting compact design good quality and low price.

If many relays are required in a device the excitation current is an important parameter. Also high voltage relays with single pole double throw contact rl 21 or for higher voltages rl 42 h and rl 38 h are available. Contact voltage rating typical control relays rated 300 vac or 600 vac automotive types to 50 vdc special high voltage relays to about 15 000 v. Voltage relays are electrical devices in which the primary function is the switching of current from one circuit to another.

A single momentary input voltage switches these relays and locks them in position so they don t require a constant input voltage to stay on or off. Geya under over voltage relay is used to provide a signal that the incoming power supply voltage is outside of a predetermined range. There is both a mechanical life and a contact life. These relays monitor three phase voltage and respond to abnormal or overcharge conditions a pre selected undervoltage threshold and a pre selected percent of phase.

52 available for 4 5 business days delivery. Simple and effective monitoring eaton s voltage monitoring relays are solid state protective relays that automatically operate when one or more phases of the three phase supply is lost or when the phase sequence is reversed. The relay is activated remotely using an electrical signal. Therefore you will find in our range a high voltage relay for much lower excitation current.
