More insight. Fewer truck rolls.

Utilities are working to improve outage response, increase feeder visibility, and reduce truck rolls. The SCADA Cellular Modem (SCM) adds a remote communications option to the LineDefender™ single-phase recloser—helping crews locate transient faults faster and restore power remotely.

The SCM enables critical use cases for utilities such as the ability to set the LineDefender recloser on an instantaneous/sensitive trip setting remotely during red flag days for wildfire mitigation or enabling an alternate profile for seasonal variations on the circuit.

Customers can order the SCM with a new LineDefender recloser or retrofit it to an installed LineDefender device in the field. It’s programmable through GridHUBB™ software—the same user-friendly platform used for the LineDefender recloser—supporting desktop or remote access via USB‑C or IP.

Remote visibility and control made easier

Designed for an intuitive utility workflow, the LineDefender SCM helps maintain visibility on laterals and supports faster outage identification and restoration. Using the LineDefender recloser's load harvesting capabilities, crews can use the SCM to restore power remotely when conditions allow—without relying on a power transformer or a separate control cabinet.
