Schneider Electric 8502 B0-80 NEMA Size 0 Motor Starter

Schneider Electric’s Square D 8502 B0-80 NEMA Size 0 motor starter is a compact, single‑phase starter designed to start and stop small motors with a load voltage up to 440 V and a control coil rated at 115 V. The unit is specified for up to 2 HP in single‑phase service, making it suitable for light‑duty equipment such as fans, pumps, or small conveyors where overload protection is provided separately. As part of Schneider Electric’s Class 8502 Type S family, these starters are built for reliable full‑voltage operation across common 50/60 Hz systems, with rated loads up to 600 VAC in many configurations. coil current specifications for the 8502 family are documented as approximately 232 VA inrush at 50 Hz or 245 VA inrush at 60 Hz, with sealed‑coil losses around 26–27 VA, which informs control circuit sizing and coil sizing in typical installations. The B0‑80 variant aligns with standard Size 0 mounting and electrical interface conventions within the Square D/NEMA starter ecosystem, facilitating straightforward replacement or integration in existing Square D installations. This makes the 8502 B0‑80 a practical choice when a compact, dependable motor starter is required for small single‑phase applications in industrial or commercial equipment.
