Schneider Electric TVS4IMA25 Surge Protective Device

Schneider Electric's Surgelogic TVS4IMA25 is a modular surge protective device (SPD) in the IMA family, designed to be installed as a replacement module within Schneider Electric's Surgelogic protection architecture to guard electrical equipment from transient overvoltages on low-voltage power circuits. The IMA family includes catalog numbers TVS1IMA__, TVS2IMA__, TVS3IMA__, TVS4IMA__, TVS5IMA__, TVS6IMA__, and TVS8IMA__, each scaled for different system configurations, with TVS4IMA__ representing the 4IMA segment of the line. Variants in the TVS4IMA family include outdoor-rated options such as TVS4IMA24O (320 VAC MCOV, 1-pole), illustrating the voltage ranges these modules support. The Surgelogic IMA line has high fault-current ratings in other models, such as IMA12 with up to 200 kA SCCR at 120/240 V, 1-phase, 3-wire, underscoring the protection these modular devices can provide across typical low-voltage distributions.
