SJ300 Inverter

Tables for 400V	Note that “General Specifications” on page 1–9 covers all SJ300 inverters, followed by
class inverters	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).
