  • 10kA short-circuit breaking capacity for higher prospective fault levels
  • Compact three-module configuration for three-phase distribution boards
  • Visible contact-position indication
  • Fast-clip mounting on standard 35mm DIN rail
  • Suitable for cable and U-type or pin-type busbar connections
Professional Installation Requirements
  • Installation, testing and maintenance must be performed by a licensed electrician in accordance with AS/NZS 3000 and applicable electrical regulations. Isolate the supply before installation or servicing.
Applications
  • Final subcircuits in residential switchboards
  • Commercial and industrial three-phase distribution boards
  • Lighting and power circuits requiring individual earth leakage protection
  • HVAC, pumps and other mixed resistive or inductive loads
  • Electrical installations requiring Type A residual-current protection
Standards & Compliance
  • AS/NZS 61009.1 for residual current operated circuit-breakers with integral overcurrent protection
Environmental Benefits
