Key Features
  • Combines overload, short-circuit and earth leakage protection in one device
  • Type A residual-current sensing responds to alternating and pulsating direct residual currents
  • C curve suits resistive and inductive loads with low inrush current
  • 10kA short-circuit breaking capacity for final subcircuit protection
  • 1P+N design in a single modular-width device
  • DIN rail mounting with fast-clip installation
  • Contact position indication for easier circuit status identification
Professional Installation Requirements
  • Installation, testing and commissioning must be carried out by a licensed electrician in accordance with AS/NZS 3000 and applicable local electrical regulations. The device rating must be matched to the circuit design and prospective fault current.
Applications
  • Residential final subcircuits
  • Commercial lighting and power circuits
  • Distribution boards and consumer units
  • HVAC and refrigeration auxiliary circuits
  • Resistive and inductive loads with low inrush current
  • Single-phase circuits requiring combined overcurrent and residual-current protection
Standards & Compliance
  • AS/NZS 61009.1:2015 for residual current operated circuit-breakers with integral overcurrent protection
Environmental Benefits
  • Combines circuit-breaker and residual-current protection in one device, potentially reducing switchboard space and material use compared with separate protective devices
  • Durable DIN rail-mounted construction can reduce replacement frequency and electrical equipment waste
  • Efficient fault protection can help limit damage to connected wiring and equipment
