Application
DZ47LE-63 is applicable to a line of AC 50/60Hz,rated voltage 230V for single pole two-wire, 2- pole or 400V for 3-pole,3-pole 4-wire, 4-pole and rated current up to 63A. It can protect the line and motor from overload and short circuit. It can also be used for infrequent line conversion and infre quent motor start. It conforms with the standards of IEC60947-2.
