Key Features
  • 50kA short-circuit breaking capacity
  • Magnetic-only trip unit for motor circuit short-circuit protection
  • 125A frame with a 25A rated current
  • Three-pole construction for three-phase circuits
  • Suitable for industrial switchboards and low-voltage distribution systems
  • Can be used with separate overload protection for complete motor protection
  • Designed for AC low-voltage distribution applications
Professional Installation Requirements
  • Installation, selection, adjustment and testing must be carried out by a licensed electrician in accordance with AS/NZS 3000, the equipment manufacturer's instructions and applicable switchboard requirements. Magnetic-only protection does not provide overload protection and must be coordinated with the motor starter or separate overload relay where required.
Applications
  • Three-phase motor circuit short-circuit protection
  • Industrial switchboards
  • Low-voltage distribution boards
  • Feeder and sub-main protection where separate overload protection is provided
  • Commercial and industrial electrical installations
Standards & Compliance
  • AS/NZS IEC 60947.2:2015 is the applicable Australian/New Zealand standard for moulded-case circuit breakers; CHINT documentation specifies IEC/EN 60947-2. Verify local certification and installation requirements before use.
Environmental Benefits
  • Durable construction and a published mechanical life of up to 25,000 cycles can reduce replacement frequency and equipment waste
  • Metal and thermoplastic components are recoverable through appropriate electrical equipment recycling streams
  • Supports reliable motor and distribution protection, helping reduce damage-related replacement of connected equipment
Warranty Information

CHINT's general warranty policy states 27 months from the date of manufacture for other low-voltage apparatus, subject to authorised sales channels, contract conditions and exclusions for improper installation, misuse or unauthorised modification.
