Moulded case circuit breaker series launched in 1956, was available in different versions and is now obsolete
ABB SACE low-voltage moulded case navy version circuit breakers consisted of the following series: SACE Isol and SACE Fusol with built in current limiting fuses.
SACE Isol series was characterized by six versions for rated uninterrupted currents Iu from 63 to 800A and breaking capacity Icu up to 25kA at 440V AC.
These circuit breakers were equipped with thermomagnetic releases for protection in the case of short circuit, either with instantaneous trip or with selective time delayed trip (for the Z 630-800/MM circuit breakers).
