MVNXATL Series Smart ATL Starters

Ratings from 2300 - 15000V up to 4000HP

Next Generation Capabilities

Benshaw Smart Across-The-Line (ATL) Starters provide full-voltage control for three-phase induction motors, with advanced protection, metering, diagnostics, and communication via the Next Generation (NX) controller. Each unit is housed in a free-standing NEMA 12 or NEMA 3R enclosure, with separate medium- and low-voltage compartments for safety, serviceability, and easy access through a door-mounted keypad.

Standard features include a load break/fault make disconnect switch, Class “R” current-limiting fuses, a vacuum motor contactor, and the NX controller with display. For installations with limited space, a compact 20” wide version is also available.
