Key Features
  • Combines overload, short-circuit and residual-current protection in one device
  • Type A detection is suitable for modern electronic loads producing pulsating DC leakage currents
  • 1P+N configuration provides phase protection with switched or uninterrupted neutral arrangement as specified
  • Compact one-module, 18mm-wide design for residential and commercial distribution boards
  • Visible contact-position indication for easier inspection and maintenance
  • C curve is suitable for general-purpose resistive and inductive final subcircuits with moderate inrush current
  • Fast clip-on installation to standard 35mm DIN rail
Professional Installation Requirements
  • Installation, testing and commissioning must be performed by a licensed electrician in accordance with applicable state or territory electrical regulations, AS/NZS 3000 and the manufacturer's instructions.
Applications
  • Final subcircuits in residential switchboards
  • Lighting and general power circuits
  • Protection of socket-outlet circuits and mixed electronic loads
  • Small commercial distribution boards
  • Low-voltage control and distribution installations
Standards & Compliance
  • AS/NZS 61009.1:2015 national differences checked for the NB3LEG-40 RCBO series
  • IEC/EN 61009-1 requirements for residual current circuit-breakers with integral overcurrent protection
Environmental Benefits
  • Combines two protective functions in one compact device, reducing switchboard space and material requirements
  • Helps limit damage to electrical equipment and reduce fire-related material loss by disconnecting overload, short-circuit and earth-leakage faults
  • Durable DIN-mounted construction supports a long service life and reduces replacement waste
