Allen Bradley Bulletin 305

Bulletin 305 starters are AC starters from Allen Bradley. They are compact and available in NEMA sizes 0 to 2. These reversing starters can reverse polyphase types of squirrel-cage motors. They can also provide full voltage starts to polyphase squirrel cage motors. Bulletin 305 starters are both mechanically and electrically interlocked. This prevents both of the contactors in the starters from being closed at the same time. Bulletin 305 starters can support Allen Bradley Bulletin 193 E1 Plus types of overload relays for additional motor protection. Some Bulletin 305 starters can support up to 600V AC of 3-phase voltage. Different Bulletin 305 starters support different continuous current ratings.
