Analysis-Customer Complaints about JONON's Leakage Circuit Breaker

 

Problem description:

The customer (Foshan area) complained about the installation of the 3P leakage circuit breaker produced by JUNON company.

 

Cause analysis

1. The customer's choice is not correct (household leakage usually uses 2P or 3P + N leakage, instead of 3P leakage, because 3P leakage is used for industrial power use and is specifically used for three-phase power grids, and if the home uses 3P leakage, Because the zero line does not pass through the mutual inductive coil, It will inevitably lead to a trip.)

2. Determination of Customer Liability
