Track Individual Circuit Electricity Usage
This 45 Amp electricity sub-meter is ideal for use in locations where you would like to know how much electricity is used by individual single-phase circuits, such as:
- Air conditioning systems
- Electric hot water systems
- Pool or spa circuits
- Refrigeration coolrooms
- Electric vehicle chargers
- Lighting circuits
- Granny flats, caravans, cabins, workshops, and more*
* For any situation that involves on-billing a tenant or sub-tenant, we recommend our NMI-approved sub-meter.
Easy to Install, Affordable Sub Meter
Gain insights: find out exactly how much electricity a particular power circuit uses. Make informed decisions about energy consumption and reduce your bills.
Easy to use: the clear LCD display shows total cumulative kilowatt hours (kWh), making it simple to track your usage.
Versatile: suitable for various applications, from monitoring a single appliance to tracking the energy usage of an entire granny flat (within the 45A current rating).
Reliable: dependable readings with class 1.0 accuracy (± 1%) and safe data storage, even after a prolonged blackout or disconnection.
Simple installation: standard DIN rail mount for easy integration into your existing switchboard (installation by an electrician is required).
This is our smallest sub-meter. For larger circuits or sites, choose a higher amp option. See our complete range of electricity sub-meters.
