## Summary description

Three-phase reactive energy meter ESH-REA 3F measures reactive energy in 3-phase electrical systems. Rated for 3×30 A with a maximum continuous current of 100 A, it records kvarh for billing and monitoring. Suitable for industrial and commercial installations, it supports standard connection schemes and provides reliable metering for power management and reactive power compensation.

## Long description

The Three-phase reactive energy meter ESH-REA 3F, 3×30 A (max 100 A) is designed to measure reactive energy in three-phase electrical systems. It records kvarh and is intended for use in industrial and commercial installations where monitoring of reactive consumption and compensation is required. The meter supports standard three-phase connection schemes and provides continuous indication of reactive energy for billing and power quality management.
Advantages
The device offers accurate reactive energy measurement across three phases with a nominal current rating of 3×30 A and the ability to withstand continuous currents up to 100 A. Its construction is suitable for integration into typical switchgear and distribution boards. The meter provides reliable long-term recording of kvarh values, supports common wiring schemes, and is intended to operate with minimal maintenance. The design emphasizes stable metering under varying load conditions and compatibility with standard installation practices.
Suitable for
 Industrial facilities monitoring reactive energy consumption
 Commercial buildings with power factor correction equipment
 Energy management and billing in three-phase installations
 Measurement for reactive power compensation systems
Key specifications
 Measurement type: reactive energy (kvarh)
 Phases: three-phase (3F)
 Rated current: 3 × 30 A
 Maximum continuous current: 100 A
 Connection: standard three-phase wiring schemes
 Mounting: panel or distribution board compatible
 Output/readout: cumulative reactive energy display
How to use
Install the meter in a dry, ventilated electrical cabinet following local electrical codes and safety standards. Connect the three phase conductors and neutral according to the selected three-phase wiring diagram; ensure proper tightening of terminals and correct phasing. Verify the rated current and, if required by the installation, use appropriate current transformers or protective devices to ensure the meter operates within its rated range. After connection, observe the meter display to confirm kvarh accumulation and check that readings respond to known reactive loads.
Usage recommendations
Place the meter where it is protected from direct moisture, excessive heat and mechanical shock. Periodically inspect terminal tightness and the integrity of insulation. For installations with currents above the rated nominal value, use suitable current transformers or ensure protective devices prevent prolonged overload. Ensure that commissioning and any maintenance are performed by qualified personnel in accordance with applicable regulations.
