circuit breaker - Greek translation – Linguee

Circuit breakers are characterised essentially by (i) their nominal rating (rating beyond which the circuit breaker is tripped and breaks the circuit); (ii) breaking capacity (maximum current which can be withstood without damage by the circuit breaker in the event of a short circuit); (iii) the number of poles (i.e. the number of conductors, from 1 to 4, which are cut simultaneously by theGet price

TRANSMISSION AND DISTRIBUTION Circuit breaker maintenance in

For sf6 gas circuit breakers, gas purity and moisture tests may be used to determine the insulation quality. For vacuum CBs, a hi-pot test can verify the vacuum integrity.
