Bulletin 305 — NEMA AC Starters


Bulletin 305 reversing starters are most commonly used for full-voltage starting and reversing of polyphase squirrel-cage motors. Starters size 0…2 are electrically and mechanically interlocked to avoid both contactors being closed simultaneously. Bulletin 305 reversing starters are available with Bulletin 193 E1 Plus electronic overload relays for additional flexibility in motor protection.
