Professional Installation Requirements
  • Installation, commissioning and protection coordination must be performed by a licensed electrician in accordance with AS/NZS 3000, the manufacturer's instructions and applicable switchboard requirements. Confirm that the magnetic-only trip characteristics and short-circuit rating are suitable for the motor circuit; separate overload protection is required where applicable.
Applications
  • Three-phase motor short-circuit protection
  • Industrial motor control panels
  • Commercial and industrial switchboards
  • Generator and machinery protection circuits
  • Distribution assemblies requiring magnetic-only MCCB protection
Standards & Compliance
  • AS/NZS IEC 60947.2:2015 is the applicable Australian/New Zealand product standard for low-voltage circuit breakers
  • AS/NZS 3000 applies to selection and installation within Australian electrical installations
  • AS/NZS 61439 may apply when the MCCB is installed as part of a low-voltage switchgear and controlgear assembly
Environmental Benefits
  • Long service life can reduce replacement frequency and electrical equipment waste
  • The MCCB is a durable, serviceable protection component that can remain in use when switchboard equipment is upgraded
  • RoHS documentation is available for the NM8N product family
