Surge Protection

Panelmount (Facility-Wide)

Protecting a facility with this parallel line is an excellent first line of defense in limiting high impulse transients to a level that is acceptable to most electronic equipment. These high-energy surge protection products are placed in parallel with panels that are susceptible to both externally and internally generated transients. Our wide range of products offers specific surge protection levels, voltage/phase configurations, and any mode protection requirement at any panel within your facility.

Liebert SI Series
Provides facility-wide surge suppression and EMI/RFI filtering at service entrance and distribution panels.
Liebert LM Series
Multi-mode surge protective device that offers continuous protection from damaging transients and electrical line noise. The system uses patented circuitry to monitor the status of all protection modes, including neutral to ground. In addition, high isolation form C dry contacts provide for remote monitoring of suppression system failure, and phase and power loss.
Liebert ACV Series (AccuVar)
A multi-phase, multi-mode distribution panel-mounted transient voltage surge suppressor (TVSS) that offers continuous protection from damaging transients and electrical line noise.
PowerSure LPM and IM Series
Protects connected equipment against electric power line disturbances and transients in medium exposure locations.
Liebert SH Series
The first hybrid product in the industry to offer a true coordinated multi-stage system of suppression. Designed specifically for the needs of the telecommunications industry, it integrates the fast response time of the Silicone Avalance Diode with the high-energy capability of the standard Liebert Interceptor MOV (Metal Oxide Varistor).
PowerSure LPL and IL Series
Protects connected equipment against electric power line disturbances and transients in low exposure locations.
PowerSure IH Series
A modular Surge Protective Device (SPD) that is capable of handling the high-impulse, potentially damaging transients commonly found at the service entrance or distribution panels.
Liebert SS Series
Utilizes advanced SAD/MOV array technology for industry leading transient suppression voltages up to 160kA surge current capacity for increased reliability.
DISCONTINUED Liebert® ATF (Interceptor Active Tracking™ Filter)
Active tracking filter that offers the highest level of facility-wide surge protection available. By closely controlling voltage at every location along the sinewave,  active tracking filter technology protects sensitive electronic equipment from the potentially damaging effects of low-energy voltage transients and the ringwaves that follow.
Liebert PowerSure Panel
Protects connected equipment against electric power line disturbances and transients in low exposure locations.
