The A16 frame size means the coil's mechanical stroke and magnetic circuit match the larger contactors in that frame range — not a universal fit across the whole A-Line, but specific to the A9-A16 group. Device mounting indicates it installs onto the contactor base, not as a standalone panel component. ## What the 277V AC Rating Means Rated for 277V AC control voltage — that's the line-to-neutral voltage on a 480V three-phase system, common in North American lighting and industrial control panels. If your contactor coil circuit runs at 277V AC, this coil holds in at that nominal voltage and drops out reliably below the pickup threshold. Verify your control transformer taps before committing the BOM line; a 240V or 120V control circuit won't pull this coil in.","metaTitle":"ZA16-42 277V AC Replacement Coil, Size A16, A-Line","metaDescription":"ZA16-42 277V AC replacement coil for A9-A16 contactors.
