Contactors, Starters, & Overload Relays
NEMA Full Voltage Reversing Starters - Bulletin 505
Bulletin 505 reversing starters are most commonly used for full voltage starting and
reversing of polyphase squirrel cage motors. Starters Size 00 through 9 are electrically
and mechanically interlocked to avoid both contactors being closed simultaneously.
Bulletin 505V vertically arranged starters are available in Sizes 0.5 in the Open Type
without Enclosure construction only. Bulletin 505 reversing starters are available with
Bulletin 592 eutectic alloy overload relay as well as Bulletin 592 solid-state overloads
for additional flexibility in motor protection.
