Title:
回路遮断器
Document Type and Number:
Japanese Patent JP5108122
Kind Code:
B2
Abstract:
A circuit breaker comprises a magnetic trip mechanism (34) configured to provide a first mechanical driving force, a low voltage trip mechanism (36) configured to provide a second mechanical driving force, a first micro switch (32) configured to generate and output a first trip signal indicating that the circuit breaker has performed a trip operation due to the occurrence of a fault current on a circuit, a second micro switch (38) configured to generate and output a second trip signal indicating that the circuit breaker has performed a trip operation due to the occurrence of a low voltage on the circuit, a first driving force transmission mechanism (31, 33) configured to transmit the first mechanical driving force from the magnetic trip mechanism to the first micro switch, and a second driving force transmission mechanism (37, 39) configured to transmit the second mechanical driving force from the low voltage trip mechanism to the second micro switch.
