IEEE C62.50-2012

The scope of this standard is to define performance criteria and test methods for plug-in (portable) multiservice (multiport) surge protective devices (MSPDs) intended to protect equipment connected to one or more metallic conductive communication line(s) and a 120 V/240 V single phase ac power service, with the neutral grounded at the service equipment. These devices are intended for installation at receptacles supplying power via a branch circuit of the installation, and jointly at receptacles or jacks delivering signals from communications services, for the purpose of providing protected power and signals to a variety of information technology equipment.
