HZ5D Series Combination switch

Purpose

HZ5D series combination switch (hereafter referred to as switch) is a new type of switch of comprehensively substituting HZ1, HZ2, HZ3
series combination switch. This switch is applicable to the general electric circuits (AC 50Hz, voltage 380V, DC 220V, current up to 60A) as
power lead-in switch to realize motor’s loaded starting, speed changing, stop and reversing, as well as converting machine tool control
circuit.
