SJ300 Inverter
Tables for 400V
class inverters
Note that “General Specifications” on page 1–9 covers all SJ300 inverters, followed by
footnotes for all specifications tables. The 400V models in the upper table below (1 to 15 hp)
include internal dynamic braking units (see “Dynamic Braking” on page 5–6).
