Key Features
  • Magnetic-only trip unit designed for short-circuit protection in motor protection arrangements
  • 800A frame with 800A rated current
  • 50kA breaking capacity at common 380–415V AC operating voltages
  • Three-pole construction for three-phase systems
  • Adjustable instantaneous magnetic trip setting from 9 to 14 times rated current
  • Suitable for use with a contactor and thermal overload relay in a coordinated motor starter system
  • Compatible with optional CHINT MCCB accessories including auxiliary, alarm, shunt-trip and undervoltage releases
Professional Installation Requirements
  • Installation, adjustment and commissioning should be performed by a licensed electrician in accordance with applicable Australian wiring rules, manufacturer instructions and the requirements of the complete switchboard or motor-control assembly. Magnetic-only protection does not provide overload protection and should be coordinated with a suitable thermal overload relay or equivalent motor-protection device.
Applications
  • Industrial switchboards and power distribution panels
  • Motor control centres and motor starter assemblies
  • Short-circuit protection for large three-phase motors when used with a contactor and overload relay
  • Commercial and industrial low-voltage distribution systems
  • Main incomer or feeder protection where magnetic-only protection is specifically required and correctly coordinated
Standards & Compliance
  • AS/NZS 60947.2 is the relevant Australian/New Zealand standard for low-voltage circuit-breakers outside the scope of AS/NZS 60898.2
  • Product family documentation references IEC/EN 60947-2; verify local certification, RCM requirements and switchboard assembly compliance before installation
Environmental Benefits
  • Metallic components can be recovered for recycling at end of service life through suitable electrical equipment recycling channels
  • Magnetic-only construction avoids electronic trip-unit components where those functions are not required
  • RoHS documentation is available for the NM8N product family
  • Durable moulded-case construction supports long service life and can reduce replacement waste
Warranty Information

CHINT’s general warranty policy states 27 months from the date of manufacture for other low-voltage apparatus sold through authorised channels; contract terms and local Australian distributor conditions may vary.
