Key Features
  • Magnetic-only trip unit for instantaneous short-circuit protection
  • 250A frame accommodates the 180A rated current
  • 36kA ultimate and service breaking capacity in the C category configuration
  • Three-pole construction for three-phase switchboards and motor circuits
  • Suitable for switchboard mains, feeder and motor short-circuit protection
  • Magnetic trip characteristics help accommodate motor starting current
  • Compatible with selected CHINT NM8N accessories for circuit status and control functions
Professional Installation Requirements
  • Installation, testing and commissioning must be carried out by a licensed electrician in accordance with applicable Australian electrical requirements. A magnetic-only breaker does not provide overload protection, so a correctly coordinated motor overload relay or other overload protection may be required for motor applications.
Applications
  • Switchboard mains and feeder protection
  • Three-phase motor short-circuit protection
  • Industrial and commercial distribution boards
  • Motor control centres and machinery panels
  • Low-voltage AC power distribution systems
Standards & Compliance
  • IEC 60947-1 and IEC 60947-2 product standards
  • AS/NZS IEC 60947.2:2015 is the applicable Australian/New Zealand standard for low-voltage circuit-breakers; verify local certification and installation requirements before use
Environmental Benefits
  • Resettable protection reduces the need for disposable fuse replacements
  • Durable moulded-case construction can support a long service life and reduce replacement waste
  • Metallic electrical components are suitable for recovery through appropriate industrial recycling processes
  • RoHS documentation is available for the NM8N product range
