Key Features
  • Three-pole moulded case circuit breaker for low-voltage power distribution
  • Magnetic-only trip unit provides short-circuit protection without thermal overload protection
  • 125 A frame accommodates a 40 A rated current
  • 50 kA short-circuit breaking capacity
  • Suitable for motor protection when used with a separate overload relay
  • Supports vertical or horizontal installation and top or bottom line entry
  • Suitable for switchboards, motor circuits and industrial distribution systems
Professional Installation Requirements
  • Installation, selection and testing should be performed by a licensed electrician. A magnetic-only breaker does not provide thermal overload protection, so motor applications require a correctly selected overload relay. Install and commission in accordance with the manufacturer's instructions, AS/NZS IEC 60947.2 and AS/NZS 3000 where applicable.
Applications
  • Motor short-circuit protection with a separate overload relay
  • Industrial switchboards and distribution boards
  • Commercial and industrial low-voltage power distribution
  • Protection of feeders and outgoing circuits
  • Main or sub-main circuit protection where the coordination study confirms suitability
Standards & Compliance
  • Applicable standard: AS/NZS IEC 60947.2:2015 for low-voltage circuit-breakers
  • Electrical installation and switchboard integration should also be assessed against AS/NZS 3000 and the applicable assembly requirements
  • Verify product marking, certification and RCM requirements for the specific Australian installation
Environmental Benefits
  • Durable moulded-case construction can support a long service life and reduce replacement waste
  • Metal and thermoplastic components can be separated for recycling at end of service life where suitable recycling facilities are available
  • Magnetic-only operation avoids continuous electronic trip-unit power consumption
