Square D™ brand SurgeLoc™ Surge Protective Device (SPD) delivers specification grade performance for service entrance or critical branch panel applications. The SurgeLoc™ SPD product utilizes a high-energy suppression circuit that provides 6–10 modes of suppression from 80,000 to 240,000 peak Amps of surge current rating per phase.* These devices feature circuity that provides not only transient surge suppression, but also noise filtration. More detailed information can be found in SurgeLoc™ Brochure1300BR1302.

Inline, copper bus bar connection.
Solid state bi-directional.
Push-to-Test on-line diagnostic display.
Audible alarm with enable/disable switch.
LED indicators indicate loss of protection, or fully-operational circuit.
High-energy parallel design for IEEE C62.41 category A, B, and C3 applications.
Available in main circuit breaker and main lug only panelboards with sub-feed circuit breakers, feed-through lugs, or sub-feed lugs.
AC tracking filter with EMI/RFI filtering up to -30 dB from 100 kHz to 100 MHz.
- Dry Contacts provide remote indication of the SPD device’s operating status to a computer interface board or emergency management system.
Surge Protection Options
|Surge Counter||Displays the combined total number of transient voltage surges detected from L–G, L–L, L–N, and N–G since the counter was last reset.|
|Remote Monitor||Displays the alarm
status of the surge protective device up to 1,000 ft
(305 m) away from the unit. This option uses the dry contacts.
