Type IMA

Internal Modular Assembly (IMA) SPDs

Square D™ IMA SPDs are installed integrally to systems for service entrance and branch panel surge suppression. Internally mounted SPDs installed next to supply busses provide maximum performance inside Square D™ systems. Built-in performance is the best way to ensure cost effective power quality.
