Stepping switch keypad — local operator interface
The VW3A28100 is a stepping switch local keypad from Schneider Electric, designed as a Motor Control Accessory for use with drives or soft starters that accept a remote keypad interface.
Irreversible mounting — field service note
The variant particularity is irreversible mounting, meaning once installed the keypad is not intended for removal. Plan the mounting location and cable routing accordingly — field swaps will require unmounting the entire assembly.
