Schneider Electric FC21MA16C Surge Protective Device

Schneider Electric Square D FC21MA16C Surge Protective Device is a dedicated surge protection solution designed for 208Y/120V, three‑phase, four‑wire electrical systems. It delivers a peak surge current rating of 160 kA and comes with an integrated 60 A breaker, enabling coordinated protection within a distribution panel. This SPD is intended to guard downstream equipment from transient overvoltages and electrical surges, helping reduce the risk of damage, nuisance trips, and unplanned downtime in commercial and light‑industrial environments that use 208Y/120V service. The FC21MA16C is part of Schneider Electric’s Square D surge protection lineup and is specified for use where robust, plug‑in protection is required at the panel level, aligning with standard 208Y/120V power distribution configurations.
