Schneider Electric 8502BO-3 Magnetic Contactor

Schneider Electric's Square D 8502BO-3 Magnetic Contactor is a Class 8502 magnetic contactor used to switch AC power in industrial control panels. It is part of Schneider Electric’s 8502 family of magnetic contactors (Type S) designed for three-pole operation in 3‑phase circuits, with overload protection provided separately. This configuration is commonly employed to control electric motors, heating loads, transformers, and capacitors in equipment where external protection is required. The model 8502BO-3 is listed as a 8502 Contactor from the Square D brand, confirming its placement within this legacy 8502 series and its role as a field-switching device for higher-load applications.
