  • More Info

    The Leviton Branch Panel Mounted transient voltage surge suppressor (TVSS) devices have been designed to protect residential as well as small commercial establishments from high voltage transients. Standardized J-Box metal enclosure with prepunched standard size knockouts simplifies flush mounting in typical frame construction environments, and provides convenient connection means to existing branch panels. Some of the features are:

    Additional Features
  • Tested to ANSI/IEEE C62.41 standards
  • Single high-energy solid-state semiconductor surge suppression circuitry per phase
  • Real-time diagnostic visual indicator shows power and suppression status for each protected phase
  • Each phase provided with independent thermal fuse protection
  • Feature a low VPR to ensure protection of sensitive electronic devices including LCD TVs, PDAs and computers
  • Standard J-Box enclosure with pre-punched standard knock-outs can be easily surface mounted in typical frame construction
  • Internal DIN rail module provides for easy replacement (on Type 1 outdoor unit only)
  • All versions are compatible with Leviton Decora Home Controls

  • Protection for whole-house lighting control systems
    While this whole house surge suppressor is great for protecting computers, TVs and other electronics, it can also protect against damage to lighting control systems such as INSTEON, X10 or Z-Wave. Voltage spikes of several hundred or even thousands of volts generated by outside sources do occasionally occur. We know of customers that have had several X10 components fail simultaneously for no apparent reason except for one clue, home control components that happened to be plugged into a surge suppressor/surge protector power strip were still functional.

    If you are going to be using a significant number of remote control light switches in your home adding a whole house surge protector will give you a good insurance policy against costly damage to both your home control system and other delicate electrical equipment in your house.

    We recommend that whole-house surge protector units be installed by a licensed electrician.

    This latest version of the Leviton Whole-House Surge Suppressor has greatly increased surge handling capacity. This surge protector unit is an essential component when installing an extensive whole-house lighting control systems. LEDs on the panel show operation status.

    FWIW the Sycom unit boasted about sells for about $50 and is rated at 10KA, only 20% of the Leviton 50KA rating.
    CET -- Arizona   3/27/2012
    Don't bother with any of these Leviton Surge Protectors. 50k is no where near enough current protection, and the other improperly listed specs tell me it's not worth $5. Joules means nothing and is not an accepted SPD standard. Also, if this is Three Phase, you can't put it on your single phase house. If it's really single phase, then it's totally mislabeled. Hire a qualified electrician to install a Sycom for you. Homeowners have no business hooking up anything like this anyway.

    Seems very well-made and easy to install, but time will tell about protection from surges. I purchased this because we had failures in the remote circuitry for two ceiling fans. The replacement cost for those far exceeded the cost of this surge protector.

    Shipped and received quickly and in good order. Instructions were clear and installation by me, a DIY guy, was a snap. My only question is, how do you know if there was a surge and it worked? I guess its a case of "no news is good news!
    PETER -- warwick, RI   1/31/2009
    All hooked up and ready to go. Good price and thanks for getting it to me so quickly
    ROBERT -- cross river, NY   12/2/2007
    It's a must have for your business!
    ANIBAL -- mexico, XX   9/5/2005
