MPACT Air Circuit Breaker (ACB) Rated from 0 to 000A the MPACT circuit breaker has been designed to meet the most stringent demands in fault detection and safe interruption thereof. Available in frame sizes: frame size ranging from 0 to 0A frame size ranging from 0 to 000A The range has been developed to be aesthetically and technically coordinated with other protective devices within the GE Power Controls industrial product ranges. The breaker range has a common height and depth and is available in both fixed pattern and drawout versions which can be manually or electrically operated. Designed to offer multiple mains connection options it also comes with a wide range of easytoinstall accessories. performance ranges* ka (Icu) ka (Icu) ka (Icu) *s shown at 0V AC compact frame sizes Frame size 0 to 0A Frame size 0 to 000A Wide range of protection settings offering full selectivity Combinations of earth fault protection Easytoinstall accessories, common to entire range imple and efficient servicing on site pecification MPACT air circuit breakers comply with the following specifications for Low Voltage witchgear: IEC 97 IEC 97 IEC 97 B E 97 VDE 06 Part 0 and Part 07 Utilisation category B Approvals ATA / KEMA & LOVAG certification in accordance with IEC 97/ B E 97. pattern and withdrawable versions or pole configuration Front and rear access connections (horizontal / vertical) Devices provided with or without protection relay Manual or electrical operation Common height and depth dimensions Builtin safety features e.g. safety shutters
