  • Supports vertical or horizontal installation
  • Top or bottom line connection options
  • Isolation function suitable for approved applications
  • IP40 enclosure protection under specified installation conditions
Professional Installation Requirements
  • Installation and commissioning must be carried out by a licensed electrical contractor in accordance with the manufacturer's instructions, applicable switchboard requirements and AS/NZS 3000. Correct coordination with the motor starter, overload protection, cabling and prospective fault current is required.
Applications
  • Motor short-circuit protection
  • Industrial control panels and motor control centres
  • Commercial and industrial switchboards
  • Low-voltage three-phase distribution boards
  • Protection of motor feeders where overload protection is provided separately
  • Main or sub-main protection where the 16A magnetic-only characteristic is suitable
Standards & Compliance
  • IEC/EN 60947-2 for moulded-case circuit breakers
  • AS/NZS IEC 60947.2:2020 is the applicable Australian/New Zealand adoption for low-voltage circuit breakers where required by the installation or procurement specification
  • AS/NZS 3000 applies to electrical installation, wiring and switchboard integration
Environmental Benefits
  • Long mechanical service life can reduce replacement frequency and associated waste
  • Metal terminals and internal conductive components can be recovered through appropriate electrical equipment recycling
  • Provides durable fault protection that can help prevent damage to connected motors and switchboard equipment
