Intermatic H10S21S1DG2 is a 7-mode surge protective device from Intermatic's surge protection line, built for 120-240 VAC 1Ph electrical service. It is classified as a Type 2 device with a surge current rating of 100kA, and it is intended for installation by a licensed electrician at the service entrance or a downstream distribution panel. This unit is equipped with an EMI/RFI filter stage to help reduce electrical noise on the protected circuits, an audible alarm that signals when the surge protection modules need attention, a Form C dry contact that can be wired to a remote indicator or building monitoring system. These features let an electrician or facility maintenance staff monitor the health of the surge protection device without opening the enclosure, which is useful on commercial and industrial services where downtime for inspection is costly.

A manufacturer spec sheet is available for this model, which an electrician can reference for panel schedule notes, wiring diagrams, and mounting dimensions before it is specified on a job.
