Description

Moulded case circuit breaker series launched in 1980, was available in different versions and is now obsolete

SACE Modul series of low voltage moulded case circuit-breaker was suitable for:

  • Rated uninterrupted current Iu from 100A to 3200A
  • Rated breaking capacities Icu up to 120kA at 380/415V AC

The series was composed of 9 physical frames: SRN-SRH 100-125, SN100-3200, SNR160, SH100-3200 and the derived versions are the following:
