- Suitable for AC-7b household motor loads when correctly derated
- Requires suitable short-circuit protection because the contactor is not designed to interrupt short-circuit current
Professional Installation Requirements
- Installation and connection to mains voltage must be performed by a licensed electrician in accordance with AS/NZS 3000, the manufacturer's instructions and applicable local electrical requirements. Select short-circuit and overload protection to suit the installation.
Applications
- Lighting circuit control
- Electric heating systems
- HVAC control panels
- Residential and commercial building automation
- Distribution boards and switchboards
- Remote switching of household appliances and low-inductive loads
Standards & Compliance
- AS/NZS 3947.4.1 for low-voltage electromechanical contactors and motor-starters is the applicable Australian/New Zealand product reference
- AS/NZS 3820 essential safety requirements apply where the equipment is classified as in-scope electrical equipment
- Electrical installation must comply with AS/NZS 3000
Environmental Benefits
- Supports scheduled and centralised control of lighting and heating loads, which can help reduce unnecessary operating time
- Durable modular construction and long mechanical life can reduce replacement frequency and associated waste
- Metallic components are generally recyclable at end of service life
- Low-noise operation supports efficient building-control applications without continuous coil buzz
