Schneider Electric L1861-S1-R29B Contactor Coil

Schneider Electric L1861-S1-R29B Contactor Coil is a replacement magnetic coil for Square D 1861-S1 size 0 contactors (the S‑Series motor starter family), designed to be energized with 120 V AC at 60 Hz to actuate the coil and switch line power to a connected load. This coil carries the L1861-S1-R29B part number and matches the 1861-S1 coil footprint, making it suitable as a field replacement for Size 0 Square D contactors used in motor control circuits. Key specifications include a 120 V AC coil rating at 60 Hz and a magnetic coil design compatible with Square D/Schneider Electric contactors; verify mounting alignment and coil footprint for a proper fit in your device. Typical applications include controlling motors for pumps, HVAC equipment, conveyors, and fans in light to general industrial or commercial installations where a Size 0 contactor is appropriate.
