What is earth leakage circuit breaker?The earth leakage circuit breaker canprotect overload and short-circuit of the circuit or motor, it can also be converted and started infrequently under normal circumstances. The earth leakage circuit breakers meet the standards of GB16917.1-2003 and IEC61009-1, the product obtains design the national patent certificate.
Do earth leakage circuit breakers work in open phase condition?The third edition (2003) of EN Standard for circuit breakers, EN 60947-2, and GB/T Standard GB/T 14048.2 (2008) prescribe that the functions of earth leakage circuit breakers should normally work even in open phase condition. Products based on the previous EN Standard (second edition) have not been approved since June, 2006.
How do earth leakage relays work?Unlike earth leakage circuit breakers, earth leakage relays do not interrupt, only detect a leakage current. A ZCT (zero-phase current transformer) is used in combination with a relay. The ZCT detects a leakage current, and then the relay sends a signal.
What is earth leakage?The electrical current that flows from the live conductor to the earth through an unintended path is called earth leakage. It may flow between their poor insulation or through a person’s body and cause electrical shock. The consequence of electrical shock may prove fatal if the leakage current exceeds the only 30mA.
