What is IC in circuit breaker?
Interrupting Capacity (IC) is the maximum fault current that can be interrupted by a circuit breaker without failure of the circuit breaker.
What is breaking capacity of circuit breaker?
Breaking capacity or interrupting rating is the current that a fuse, circuit breaker, or other electrical apparatus is able to interrupt without being destroyed or causing an electric arc with unacceptable duration.
What is the difference between ICS and ICU of circuit breaker?
Ics – service short-circuit breaking capacity Icu – ultimate breaking capacity. The breaker can break this fault current, but it may not be usable afterwards. Ics – service breaking capacity. As per Icu, but the breaker remains usable.
When to trip a circuit breaker in a spa?
Use this procedure if the spa continually trips the breaker during operation. This is intended for use by spa service technicians only.
