Terasaki - Ar Acb Body Size Ar3 3200A 3P 85Ka Non Auto W/Mtr 240V Ac - ARB3323NAMSTD

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: ANSI C37.13 EN 60947-2 IEC 60947-2 NEMA SG3 JIS C 8372
