Key Features
  • Combines overload, short-circuit and earth leakage protection in one device
  • Type A residual current detection responds to sinusoidal AC and pulsating DC residual currents
  • C curve suits resistive and inductive loads with moderate inrush current
  • 1P+N configuration for single-phase final subcircuits
  • 10kA rated short-circuit breaking capacity
  • Contact position indicator for visual status confirmation
  • Compatible with cable, U-type busbar and pin-type busbar connections
  • Compact DIN rail mounting format
Professional Installation Requirements
  • Installation, testing and maintenance must be performed by a licensed electrician in accordance with AS/NZS 3000, the manufacturer's instructions and applicable local electrical regulations.
Applications
  • Residential final subcircuits
  • Commercial and light industrial distribution boards
  • Protection of power, lighting and equipment circuits
  • Single-phase circuits requiring combined overcurrent and 30mA residual current protection
Standards & Compliance
  • AS/NZS 61009.1:2015 for residual current operated circuit-breakers with integral overcurrent protection
  • SAA approval and RCM certification for the NB3LEU product series
Environmental Benefits
  • RoHS declaration supports reduced use of restricted hazardous substances
  • Energy Limiting Class 3 construction can reduce let-through fault energy and associated equipment damage
  • Reusable DIN rail design supports servicing and component replacement rather than complete board replacement
  • Long electrical and mechanical endurance can reduce replacement frequency and product waste
