Key Features
  • Combines miniature circuit breaker and residual current protection in one device
  • Protects three-phase final subcircuits against overload, short circuit and earth leakage
  • Type A detection responds to sinusoidal AC and pulsating DC residual currents
  • C-curve characteristic is suitable for mixed loads and equipment with moderate inrush current
  • Four-pole configuration includes a switched neutral pole
  • 10kA rated short-circuit breaking capacity
  • DIN rail mounting for distribution boards and switchboards
  • Includes test function for checking residual current operation
Professional Installation Requirements
  • Installation, testing and commissioning must be performed by a licensed electrician in accordance with AS/NZS 3000 and applicable local electrical safety requirements. Confirm that the RCBO rating, fault level, neutral arrangement and enclosure are suitable for the installation.
Applications
  • Three-phase final subcircuits
  • Commercial and industrial distribution boards
  • Residential three-phase circuit protection
  • Mixed resistive and inductive loads
  • Motor, pump and HVAC auxiliary circuits where a C-curve device is appropriate
  • Overload, short-circuit and earth-leakage protection in low-voltage AC installations
Standards & Compliance
  • AS/NZS 61009.1:2015 residual current operated circuit-breakers with integral overcurrent protection
  • AS/NZS 3000:2018 electrical installations and selection of protective devices
  • SAA approval and RCM marking requirements applicable to the approved NB3L-40 range
Environmental Benefits
  • Complies with EU RoHS 2.0 restrictions on hazardous substances
  • Integrated protection can help reduce damage to connected equipment and associated replacement waste
