- DIN rail compatible for modular switchboard installation
- Can be connected from the top or bottom
- Compatible with selected CHINT modular accessories
- Designed for use in AC circuits up to 240/415 V
Professional Installation Requirements
- Installation, testing and maintenance must be performed by a licensed electrical worker with the supply isolated, using correctly sized copper conductors and observing applicable Australian wiring rules and switchboard requirements.
Applications
- Domestic consumer units and distribution boards
- Commercial electrical switchboards
- Light industrial control and distribution panels
- Protection of lighting, socket-outlet and general-purpose final circuits
- Circuits supplying resistive and moderate-inrush inductive loads
Standards & Compliance
- AS/NZS 60898.1:2024 is the applicable Australian/New Zealand standard for household and similar AC miniature circuit-breakers; the manufacturer documentation specifies IEC/EN 60898-1, so local certification and approval should be verified before installation.
Environmental Benefits
- Thermal-magnetic protection can help prevent equipment damage and premature replacement following overload or short-circuit faults
- Metal and polymer components can be separated and directed to appropriate recycling or industrial waste streams at end of life
- Long mechanical and electrical operating life can reduce replacement frequency and associated material waste
Warranty Information
CHINT warranty policy states that other low-voltage apparatus is covered against defects in materials and workmanship for 27 months from the date of manufacture when purchased through authorised sales channels; contract terms may vary.
