Applications
- Domestic distribution boards
- Commercial switchboards
- Control panels and sub-distribution boards
- Circuits supplying transformers, motors, lamps and other loads with high inrush current
- Overload and short-circuit protection for AC final and sub-circuits
Standards & Compliance
- Designed and tested to IEC/EN 60898-1; AS/NZS 60898.1:2024 is the applicable Australian/New Zealand standard for AC circuit-breakers of this type. Verify RCM marking and local approval requirements before Australian installation.
- Installation must comply with AS/NZS 3000 Wiring Rules.
Environmental Benefits
- Thermoplastic housing and metal components can be separated for recycling at end of service life
- RoHS declaration is available for the NB1-63/NB1-63H product family
- Long mechanical life can reduce replacement frequency and associated material waste
- DIN rail mounting allows replacement of the breaker without replacing the complete switchboard assembly
