NEMA size - Wikipedia
NEMA (National Electrical Manufacturers Association) contactors and motor starters are rated by sizes. These sizes are grouped by rated current and power. [1] [2]
All wire rated 167 °F (75 °C) or higher must be sized per the local Electrical Code for 167 °F (75 °C) wire. (1) Contact your local Allen-Bradley distributor or Rockwell Automation sales office. This rating is for the size 6 contactor coil only. All starters …
A two-piece spring latch contactor design makes coil removal or replacement fast and simple for Sizes 00-2. The NEMA Size 3-5 features a quick change coil assembly which makes coil removal and replacement fast and simple. Coil terminals are located on top for easy accessibility. The Size 00 and 0 contactor magnet coils have three

CR305 contac tors are suitable for use on a circuit capable of delivering not more than 5,000 RMS symmetrical amperes, 600 volts maximum when protected by H, J, K1, K5, RK1, RK5 class fuses, or a circuit breaker having an inter rupting rating not less than 5,000 RMS symmetrical amperes. Remove all packing.
The Bulletin 300-E contactor family, along with a wide range of a ccessories, provides the most co mpact and flexible NEMA contac tor system available. Coil voltage code and terminal position—see page 9.
