Schneider Electric 8502PC3.10E Control Relay Contact

Schneider Electric Square D 8502-PC3.10E is a control-relay contact designed to accompany Square D Class 8502 NEMA starters and contactors. This model operates on a 110/120 V AC coil and is listed as Series B in common references, with the PC3.10E suffix identifying a specific auxiliary-contact configuration within the 8502 family. The unit serves as a control-contact element used to signal or interlock in industrial control circuits, allowing control logic to actuate auxiliary devices without carrying main-load currents in the same path. It is typically found in panel assemblies and machine controls that rely on robust Square D 8502-series components for consistent interfacing between control logic and motor or line-voltage circuits. When selecting a replacement or companion parts, verify compatibility with the 8502 line of contactors and the corresponding 110/120 V control accessories to maintain correct coil voltage and electrical fit.
