1. Application
DZ47LE-63 is applicable to a line of AC 50Hz/60Hz, rated voltage 230V forsingle pole two-wire, 2-pole or 400V for 3-pole, 3-pole 4-wire, 4-pole andrated current up to 40A. It can protect the line and motor from overload andshort circuit. It can also be used for infrequent line conversion andinfrequent motor start. It conforms with the standards of IEC61009.
