WEL7LE Series Miniature Leakage Circuit Breaker
Product number:
Classification:
Summary Description:
WEL7LE-63 series miniature leakage circuit breakers are integrated, miniaturized and leakage protection circuit breakers. They are mainly suitable for protection distribution lines with AC 50Hz (or 60Hz), rated working voltage of 230V and rated current of 63A. They can effectively prevent indirect contact electric shock and electrical fire accidents, especially electric shock accidents caused by direct contact of human body with phase lines, it is used for personal electric shock and equipment leakage protection and for infrequent connection, disconnection and conversion of lines.
