The A16-40-00-34 is a 4-pole contactor from the A16 series, with a dual-voltage coil rated 208 V at 60 Hz and 175 V at 50 Hz.
Sourcing and Fit Decision
For a procurement buyer holding a BOM line with A16-40-00-34, the key fit check is the coil: 208 V at 60 Hz or 175 V at 50 Hz. If your control voltage matches that dual-range coil, this contactor is a direct swap. The four-pole configuration suits applications needing a switched neutral or a second load circuit alongside the three-phase motor.
