How to read a Square D general duty safety switch catalog number.
D is general duty fusible and DU is general duty non-fusible. Next digit is poles (1, 2 or 3). Next is voltage (1 = 120 Vac plug fuse, 2 = 240 Vac). Last digit is amps (1 = 30, 2 = 60, 3 = 100, 4 = 200, 5 = 400, 6 = 600 A). N adds a factory neutral. Enclosure suffix: none = Type 1, R = 3R, RB = 3R with bolt-on hub provision.

- 200 to 600 A general duty switches carry more value than 30 and 60 A units.
- New surplus in the carton brings the most; loose used 30 A units carry little value individually.
- Bulk lots of the same catalog number are easier to place than mixed singles.
- We do not publish prices. Metal, demand, and condition move them. You get a written number for your unit.
Square D general duty numbers follow the same pattern as heavy duty but the voltage digit is 1 or 2 only, because general duty is a 240 V line. The 1 voltage code marks a 120 V plug fuse switch like the D211N. Factory modifications are not offered on general duty switches.
