Schneider Electric 331 300 Series Surge Protective Device, 120/240V AC, 80kA/Phase (EMC-240B)

Protect sensitive systems and reduce costly downtime with the Schneider Electric EMC-240B surge protection module. Designed as a compact, panel-mount surge protective device, the EMC-240B defends critical AC distribution panel circuits and 120/240V AC branch feeds using MOVs with thermal fusing and a failsafe fused design. Rated at 80kA per phase and compliant with UL 1449 Third Edition, it delivers fast response surge suppression ideal for protecting security and surveillance infrastructure, access control panels, network switches, NVRs, and other monitoring and IT equipment. The unit’s clear operational status indicators simplify maintenance and verification, while the 5-year limited warranty provides long-term assurance. Easy to install on standard single-phase (L, N, G) circuits, the EMC-240B is a practical choice for integrators and facility managers who need reliable surge protection integrated into low-voltage and electrical distribution systems. Add the EMC-240B to your next security or network protection plan to keep cameras, recorders and control systems online—contact sales or order now to specify on your project.
