The Bulletin 505 series is a line of Allen Bradley starters, contactors, and overload relays that are NEMA-rated. This series includes solid-state overload relays and eutectic alloy overload relays. Devices in the Bulletin 505 series are available in NEMA sizes 00 to 9. Many Bulletin 505 starters are reversing starters that support full voltage starting and reversing functions for polyphase squirrel cage motors. Starters in this series are mechanically and electrically interlocked to prevent both contactors from being closed at the same time.
