MR Relay Series
Heavy duty construction and long-term performance. Time-proven electromagnetic design that provides high compression, low audible noise and minimum eddy current heating. Open air contact.

Configurations:

  • One or Two pole
  • Normally Open or Normally Closed
  • 30, 60 or 100 amp

    • MTR Relay Series
    Best for those who prefer mercury tube contactors that are hermetically sealed, have no contactor wear points, no spark operation and only one moving part - a ceramic plunger that electrically opens or closes the load circuit.

    Configurations:

  • One, Two or Three pole
  • Normally Open or Normally Closed
  • 30, 60, or 100 amp

    • RLY Relay Series
    An inexpensive control relay that outperforms throw-away type units that are sealed or difficult to repair.

    • Group Lighting Control
    RCOC® Relay combined with an oil or vacuum switch to energize the transformer serving a dedicated lighting circuit.

    For parking lots, athletic fields,
    street and area lighting.

    Lighting Control Centers
    For situations where self-controlled luminaries are impractical due to space limitations or the number of lamps exceeds five or six.

    Configurations:

  • Two pole
  • Hand-off auto switch for daytime testing
  • Single photo-cell system control
  • 120/240 or 240/480 VAC

    • A lighting system designer generally has a choice of using a multiple relay or individual lamp controls. In some cases, self-controlled luminaries are a good option. However, when the lighting system must extend beyond a confined area or the number of lamps exceeds five or six, a multiple relay should be considered. Multiple relays offer several unique advantages:

    • Single-point maintenance
    • Primary circuits are energized only at night
    • Lightning protection available for the load, line, and control circuits
    • Circuitry can be de-energized for service safely day or night
    • All lamps come on and go off at the same time
    • Only one control is required
