Description

Surgelogic™ Type SDSA is used mostly in service entrance panels to provide an efficient and economical means of surge suppression. The surge suppressors use two pole spaces in a QO™ or Homeline™ load center, or NQ panelboard. SPD are three phase and are rated for use in an indoor or outdoor enclosure. Ideal for residential and light commercial use, these SPDs provide a dependable first layer of surge protection. Meter Socket has no By-pass. It is designed to protect electrical service and major household appliances, excluding electronic devices. Designed for 4 wire 208Y/120VAC three phase systems. Securing up to 50kA surge current per phase. This surge protection device is UL Listed.

Features

Protective Device (SPD) per UL 1449 4th Edition standards, this Square D by Schneider Electric unit delivers complete design flexibility. It can be installed safely on either the line or load side of your main electrical service entrance, allowing plant electricians to isolate upstream utility surges before they ever penetrate the facility distribution panel.
This Surgelogic device features a 40 kA peak surge current rating per phase and a 10 kA nominal discharge current (In). This ultra-fast suppression architecture clamps incoming lightning strikes and utility switching transients in microseconds, safeguarding automated production lines and building electronics from catastrophic voltage breakdown.
This heavy-duty module is engineered precisely for 3-phase, 4-wire Wye (Star) electrical setups rated at 208Y/120V AC.
Designed with an integrated local signaling window, the device utilizes a high-visibility green status LED for instantaneous diagnostic tracking. As long as the LED remains lit, your downstream three-phase infrastructure is fully secure; if the light goes out, the module has sacrificed itself during a surge event and requires replacement. The compact 3.07" x 3.62" chassis includes pre-wired #12 AWG copper leads to ensure a swift, direct back-nipple or panel-mount installation.
