Square D 8502SBG2S Contactor

The Square D 8502SBG2S is a three‑pole contactor housed in a NEMA Type 1 enclosure for a NEMA Size 0 frame, designed to switch loads in industrial control panels. It belongs to Square D’s 8502 class of magnetic contactors used to switch heating loads, capacitors, transformers, and electric motors when overload protection is provided separately. This model supports open‑type and Type 1 enclosure installations, with dimensional guidance documented in the 8502 family catalogs and related 8502CT9701 references. As part of the 8502S family, the 8502SBG2S is intended for general industrial control circuits requiring compact, reliable switching for multiple loads; coil‑voltage options exist within the family (for example, 8502SBG2V02S variants), so the exact coil configuration depends on the variant selected for a given panel.
