Key Features
- 100kA maximum discharge capacity for high-exposure surge environments
- Type 2 protection for transient overvoltage in low-voltage distribution systems
- 440V maximum continuous operating voltage for three-phase applications
- Three-pole configuration for main switchboard installation
- Remote signalling contact for connection to building management or alarm systems
- Replaceable plug-in protection modules allow servicing without replacing the complete base
- Visual status indicator identifies damaged protection modules
- Thermal overload and ageing protection
- DIN rail mounting for switchboards and distribution boards
Professional Installation Requirements
- Installation and connection should be performed by a licensed electrician in accordance with the manufacturer's instructions and AS/NZS 3000. Correct upstream overcurrent protection, earthing, conductor sizing and coordination with other SPDs must be verified before commissioning.
Applications
- Main switchboards
- Three-phase commercial electrical distribution boards
- Industrial control and power distribution panels
- Building management systems requiring remote SPD status monitoring
- Protection of low-voltage electrical equipment from lightning-induced and switching transients
Standards & Compliance
- AS/NZS 3000 for electrical installation, wiring and earthing requirements
Environmental Benefits
- Replaceable protection modules extend the service life of the DIN rail assembly and reduce replacement waste
- Modular construction supports targeted replacement of damaged cartridges rather than the complete device
- RoHS-related restricted-substance compliance supports reduced use of hazardous materials
- Protection against transient surges can help reduce premature failure and electronic equipment waste
