Surge protective device (SPD) units protect electronic equipment from transients. The I-Line® Plug-On Unit with Surgelogic® Surge Protective Device (SPD) is a modular parallel surge protective device designed for service entrance, distribution, or branch panel applications. The device is a multi-stage suppression circuit consisting of field-proven, fast-acting 34 mm metal oxide varistors (MOVs). Each MOV is thermally protected for low current faults, and each module is fused.
The I-Line plug-on unit with a Surgelogic surge protective device is a high performance surge suppressor package incorporating individual modules for each phase. Modes of protection include:
A filter provides EMI/RFI noise filtering. The suppression elements are encapsulated in a UL® Recognized thermosetting epoxy material—another performance element that provides additional protection.
Each surge suppression module is individually fused and uses circuitry with thermal cutouts to isolate the SPD and ensure shutdown in the event of MOV damage during severe overvoltages—even when operated on high fault current power systems. Online diagnostics continuously monitor the unit status, and LEDs signal a loss of a suppression circuit. An audible alarm with an enable/disable feature and dry contacts are included in the standard diagnostic package.
Design Features
• Same easy installation as I-Line circuit breakers• Requires 13.50 in. (343 mm) of mounting space• FC units mount in the same mounting slots as FA circuit breakers. FI units
mount in the same mounting slots as KA circuit breakers• Can be applied in a six-disconnect panel or switchboard (SPD counts as
one disconnect)• High-energy parallel design for ANSI/IEEE C62.41 and C62.45
category B and C3 applications.

Surgelogic® Surge Protective DeviceApplication Information
The effects of lightning and the damage caused by lightning-generated transients are well known. The failure of electronic equipment in a facility located in a high lightning area can easily be attributed directly to lightning-generated transients. Transient protection can be installed on the power distribution system to protect this equipment from these externally generated transients. Lower magnitude transients generated within a facility and their effect on microprocessor-based equipment are less obvious than the transients induced by lightning. Transient voltage generated from inductive motors, pumps, electric welders, etc., may not be large enough to cause immediate damage, but they can cause equipment to malfunction.
A damaging transient voltage can enter a facility from several locations. The highest level of protection should be provided at the service entrance. A second level of protection should be provided at distribution points serving critical areas, for example, computer rooms, accounting areas, and laboratories. Other facility entry points that should be protected include panels serving outdoor lights, or outdoor equipment such as motors. Protection should also be provided for critical areas with equipment essential to the company.
Square D® brand SPD products offered by Schneider Electric provide protection at every level of the electrical distribution system. Typical applications include:
