Residual Current Circuit Breaker
Product Code : DZ47LE C45LE
Product Description

Product Description:

DZ47LE C45LE Residual Current Circuit Breaker with Over Current Protection 

1. Application 

DZ47LE-63 is applicable to a line of AC 50Hz/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 40A. It can protect the line and motor from overload and short circuit. It can also be used for infrequent line conversion and infrequent motor start. 
It conforms with the standards of IEC61009.
