Terasaki - Ar Acb Body Size Ar4 4000A 3P 100Ka W/Ocr21Cl/Sht - ARB4403STD

Features
 • Super fast clearance of short circuits, minimises the thermal and mechanical stress on busbars during an electrical fault
 • Unique 'Double Break' contact mechanism provides excellent mechanical and electrical endurance reducing life cycle costs
 • High short time withstand rating (I) providing superior selectivity and ensuring a reliable power supply
 • Isolating clusters on body, allow complete ACB circuit to be replaced and maintained without shutting down the switchboard
 • On-board energy management monitoring which facilitates energy usage reporting
 • Standards Compliance: IEC 60947-2 EN 60947-2 JIS C 8372 NEMA SG3 ANSI C37.13
