Monitoring module for a remote feed circuit breaker and monitoring method

摘要

Around a module for monitoring a remote feed circuit breaker, which can be switched in the operating state in a circuit between a remote feed network and the remote feed circuit breaker and which can be moved between a conductive state that connects the remote feed circuit breaker to a blocking state blocking the remote feed circuit breaker, which prevents the risk of fire due to defective switch diodes it is proposed that the module have a loop-like circuit, the circuit having means for measuring a network voltage Umess in a network monitoring branch, a triggering branch being provided in order to trigger a change between the conducting state and the blocking state depending on the mains voltage U.
