GE RR7 - 20A SPST Low Voltage Relay Total Lighting Control

Discontinued item. Low stock. While supplies last.

GE Model RR-7 isa mechanical latching-type unit requiring only momentary 24 VAC switch circuit pulses to open or close line voltage circuits.

All GE low voltage relays may be used to full-rated capacity for tungsten filament, ballast, or resistive loads.

  • General information: UL listed, CSA certified; mounts in standard 1/2" K.O. - 0.865" to 0.875" (nominal 22 mm) dia - in 14- or 16-gauge material; operates in any position
  • Operating voltage: 24-29 VAC (±10%) half or full wave rectified or pure, 30-38 VDC (±10%) filtered
  • Min activating pulse: 50 ms
  • Coil impedance: 75-85© @60 Hz unrectified 55-60© DC resistance
  • Coil inrush current: 325 mA @ 24 VAC
  • Contacts: SPST maintained (mechanical latching)
  • Weight:  0.3 lb (0.12 kg)
  • Terminals: Two terminals, two back wiring holes per terminal for use with #14-10 AWG solid or stranded wire (copper wire only)
  • Lamp load: 20A tungsten filament 125 VAC 20A ballast 277 VAC
  • Resistive load: 30A 277 VAC
  • Motor load: 1/2 hp @ 110-125 VAC 1/2 hp @ 220-277 VAC
  • Temp: 32° to 140°F (0° to 60°C)
  • Relative humidity: 10% to 95% RH non condensing
  • Dimensions: 1.375"W x 1.6875"L x 2.375"H (3.5 x 4.29 x 6.03 cm)
  • Endurance: 50,000 cycles, full load 100,000 cycles, no load.
  • Lead length: 6" (15 cm)
The relay employs a split low-voltage coil to move the line voltage contact armature to the on or off latched position. The on coil moves the armature to the on position when a 24 VAC control signal is impressed across its leads.
This is analogous to a magnet attracting the handle of a standard single-pole switch to the on position when energized.
The armature (handle) latches in the on position and will remain there until the off coil is energized, drawing the armature into the off position. This control operation provides several key control features:

Positive action

The relay always goes to the state commanded. For example, multiple off commands will simply keep the contacts in the off position.

Stable operation

Since the relay latches in the on or off position, power outages do not result in a change of state.

Minimal power consumption

Control power is only required when the relay changes state.

Additive control functions

Pulse control signals coupled with latching allow any number of switches or electronic control devices to operate the same relay. The relay position is always dictated by the last signal.



Important Considerations and Restriction

  1. Relays connected in parallel - Two or more relays connected in parallel will operate together.
  2. Do not use these relays to switch DC loads. Doing so will damage the power contacts.
  3. For longer life, use half-wave rectified AC voltage for relay control.

  1. Replacement for one that only lasted less than a year

    Posted by Unknown on 12th Dec 2015

    Purchased this to replace a defective relay that lasted less than a year. The original relay has lasted over 40 years in a residential application. I am hoping this one will last as long as the original. Time will tell so its too early to know if the first replacement was a fluke or the complete lot is defective.

Condition: New In stock
