REMOTE MONITORING SYSTEM USING THE EARTH LEAKAGE CIRCUIT BREAKER WITH SURGE PROTECTOR

摘要

PURPOSE: A remote monitoring system is provided to reduce installation costs and time by arranging an earth leakage circuit breaker inside a surge protector. CONSTITUTION: A surge protector(100) includes a power breaker controller and a surge breaker controller. The power breaker controller includes a power breaker(112) and a power contact signal generator(120). The power breaker breaks power when a load current or leakage current above the rated capacity occurs. A power contact signal generator generates the power contact signal which shows a power supply status. The surge breaker controller includes a surge breaker(122) and an alarm contact signal generator(134). The surge breaker breaks the surge above the rated capacity. The alarm contact signal generator generates a surge contact signal.
