Frequently Asked Questions
What is meant by the term instantaneous trip?
Instantaneous tripping indicates that no delay is deliberately introduced in the tripping action of the circuit breaker during short-circuit conditions.
What is an interrupting rating?
It is the highest current at rated voltage available at the incoming terminals of the circuit breaker. The interrupting rating of the circuit breaker must be equal to or greater than the available short-circuit current at which the circuit breaker is applied to the system.
What is the purpose of a trip indicator?
It is a type of module that mounts directly to the circuit breaker trip unit and displays whether the circuit breaker has tripped due to overload, short-circuit or a ground fault condition.
