The A3PP42-6L5G-11 is a 44mm maintained pilot device with an integral 120V transformer, green lens, and 1 normally-open plus 1 normally-closed contact block. The transformer lets it operate directly from a 120V control supply without an external step-down — useful in panels where the control voltage is already 120VAC and you need a local maintained signal (like a run-permit or mode-selector indication) in a standard 44mm cutout.
Sourcing posture
No official successor order code is listed, so a direct cross-reference is not available from the manufacturer; any replacement would need to be evaluated against the panel cutout (44mm), the 120V transformer requirement, and the 1NO+1NC contact arrangement.
