Essential Info

The Intermatic IG1240RC3 Whole House Surge Protector features six modes of protection and is recommended for residential and light commercial applications. It is intended for installation on 120/240 volt AC panels. The Whole House Surge Protector incorporates the newest developments in MOV (metal oxide varistor) technology and provides individual component thermal protection and monitoring. The failure of a single component will turn the LED indicator OFF and turn the alarm indicator ON. The "All Mode" protection configuration provides distinct protection paths between every conductor in the electrical system. When installed on service entrance or main panels with a common neutral-ground bus, line-to-neutral and line-toground protective circuits are paralleled for redundancy and maximum current capability. On sub-panels with separate neutral and ground busses, protection is provided against all possible modes of surge energy with distinct line-to-neutral, line-to-ground, neutral-to-ground and line-to-line protection components.



  • CONFIGURATION: Parallel technology permits installation over a wide range of applications and ampacities. Compact design provides a small footprint for easy installation
  • PROTECTION MODES: All Mode protection; line to line, line to neutral, line to ground and neutral to ground
  • COMPONENTS: Board configuration provides Very Low Impedance (VLI) surge paths
  • THERMAL PROTECTION: MOV’s contain thermal detection (TDC) and protection. Components react to excessive heat stress at each component location and will trigger the TDC to decouple the affected suppression component
  • OPERATIONAL INDICATORS: Dedicated circuits monitor each component in each mode and control the operation of each phase LED indicator. Lighted green indicator(s) represent normal power-on and unit operational condition. A red indicator will light if protection is reduced or lost
  • ENCLOSURE: NEMA 4 type polycarbonate (Noryl)
  • MOUNTING: Two tabs molded into unit housing are located on two faces. Unit may also be mounted by use of the ½" offset nipple
  • WIRING: 30" of 14 gauge stranded copper wire is preconnected for each phase, neutral and ground. Wires exit the enclosure through a ½" nipple located at the left side of the enclosure
  • WIRE COLOR CODE: Black - phase leads, White - neutral lead, Green - ground lead
  • WEIGHT: 2.85 pounds, 3.27 pounds in carton, 13.65 pounds in master carton of four units
  • AMBIENT OPERATING TEMPERATURE: - 40 to + 85 OC (- 40 to + 185 OF)
  • AGENCY LISTINGS: UL 1449 - 2nd Edition; cULus
  • Important notes:
    Defective exchanges for identical item within 30 days of purchase. After 30 days, please contact the manufacturer.

IG1240rc3 SURGE Protection device, Yes easy to install but if you read the back paper work that comes with surge What is not covered by this warranty Damage due to direct or VICINTY ? lightning strikes ? Not intended to provide protection during utility voltage SWELLS ? or loss of neutral condition. Question to me a SWELL SOUND LIKE A SURGE!

    GERALD -- elkton, VA   1/26/2013
    A "must have" to protect all your modern electronics. Easy to install, maintenance free. Only the fraction of the cost of a new tv!
    DIRK -- parrish, FL   1/11/2013
    We just moved into this house that had an FPL whole house surge protector installed. The monthly cost would have been $10. We had it removed and had an electrician install this Intermatic instead. The cost/benefit is obvious and the green light is reassuring. Just an excellent investment.

    I Rate my firsttime with Smarthome as 5 Star. I had to return the item because the manufacturer had left two screws inside the electric surge suppressor and you quickly responded with a replacement. Thank you, R. Mele
    RICHARD -- poland, OH   9/17/2012
    Your service was great and fast and efficient. I did have a problem with the surge supressor and you advised to contact the manufacturer which I did. There was a rattle inside the suppressor and they advised I return it to Smarthome. I contacted you and you sent me a retu8rn label. I mailed the suppressor to you Aug 14, 2012 and requested a new replacement surge suppressor from you. Thank you for your quik assistance in resolving my product issue. Richard Mele

    Its installed and working great.We had a power outage on 6/30/12 and everything is fine with it.
    RONALD -- albuquerque, NM   2/28/2012
    A little difficult finding a knockout that allowed unit to fit without interfearing with out wiring. Otherwise not hard to install and seems to be doing the job.
    DAVID -- lompoc, CA   11/26/2011
    Seems to work as described but won't know unless a surge happens
