General Information

Euclid™ DC Relays are built to withstand severe service.  They are recommended for use on heavy industrial equipment, such dc drives as cranes and mill auxiliaries.

Application

• VOLTAGE RELAYS

  "VR" voltage relays are used for reversing-plugging controllers with Emergency or Service Dynamic Braking, and for armature shunt contactors on multi-step slowdown circuits.

  "JK" voltage relays are used for initiating high speed lowering on hoist controllers.

  "LSR" is a Limit Switch Relay standard for hoist control panels with power limit switch.

  "NP" is a Non-Plugging Relay for compound and shunt motors.

  "PR" Plugging Relays are rectifier type used on dc reversing plugging control panels to limit motor torque during plugging operations.
  

• CURRENT RELAY

  "FL" Field Loss relay is recommended to protect against loss of field power on compound or shunt motors.
  

• DC CONTROL RELAY

  "PA" Control Relays are general purpose DC Relays with 2, 4, or 6 form C contacts. Available with 115 VDC or 230 VDC coils
