The Enistic Smart Meter SUB3 (3 x 100A) and SUB3-600 (3 x 600A) are high-accuracy energy meters suitable for residential, office and industrial energy metering applications.

The meter can be used in single or three phase modes. Wireless communications, DIN mount fitting and external current clamps make for simple installation. A push-button display on the front of the meter allows for selective display of energy, power, voltages and currents in each of the phases.

The Fiscal kWh Meter has a number of application areas:

• Metering of single phase or three phase circuits
• Billing and bill apportionment
• Metering residential, office and industrial energy use
• Analysis of power factor quality
• Metering the energy use of a large plant.

Its features include:

• High-accuracy design
• Available in 300A (3 x 100A) or 1800A (3 x 600A) configurations
• Manufactured to comply with international standards IEC 60687/61036/61268 and IEC 62053-21/62053-22/62053-23
