Key Features
- 500A rated current in an 800A frame
- Three-pole configuration for three-phase systems
- Magnetic-only trip unit intended for motor protection arrangements
- 36kA short-circuit breaking capacity
- Adjustable magnetic instantaneous protection
- Suitable for industrial switchboards and high-current distribution assemblies
- Can be installed vertically or horizontally with top or bottom line entry
- Compatible with selected auxiliary, alarm, shunt-trip and undervoltage accessories
Professional Installation Requirements
- Installation, commissioning and maintenance must be carried out by a licensed electrician in accordance with the approved switchboard design, manufacturer instructions, AS/NZS 3000 and applicable high-current electrical safety requirements. The magnetic-only release does not provide thermal overload protection, so a correctly selected thermal overload relay is required for motor protection systems.
Applications
- Industrial switchboard mains protection
- Three-phase motor protection using a contactor and separate thermal overload relay
- High-current power distribution
- Commercial and industrial electrical distribution boards
- Short-circuit protection for large motor control assemblies
Standards & Compliance
- AS/NZS IEC 60947.2:2015 — applicable Australian/New Zealand standard for low-voltage circuit-breakers; verify product-specific conformity documentation before installation
- AS/NZS 3000:2018 — electrical installation requirements applicable to the surrounding installation and switchboard
Environmental Benefits
- Durable moulded-case construction can support a long service life and reduce replacement waste
- Metal components and copper conductors are recyclable at end of service life
- RoHS documentation is available for the NM8N product series, subject to the supplied product configuration
