Compact DIN-rail mounting enables easy installation in distribution boards and energy management setups.

## Long description

ProBase 3F-ESH-TRA is a three-phase electricity meter designed for measuring active electrical energy in 3x230/400 V systems with a nominal current of 6 A. The compact DIN-rail housing fits standard distribution boards and is intended for commercial and small industrial applications where accurate kWh metering and integration with building energy management are required. The meter provides precise cumulative energy readings and supports serial communication for remote reading and monitoring.
Advantages
The meter offers precise active energy measurement in three-phase networks with a low-profile DIN-rail form factor that simplifies installation in distribution panels. Its nominal current rating and measurement range are suitable for installations where space is limited but accurate consumption tracking is necessary. Built-in communication capability enables connection to external monitoring systems, making centralized energy tracking possible without replacing existing infrastructure.
Suitable for
 Commercial premises energy monitoring
 Small industrial installations and workshops
 Tenant submetering in multi-occupancy buildings
 Integration with building management and SCADA systems
Key specifications
 Supply and measurement system: three-phase, 3x230/400 V
 Nominal current: 6 A
 Measurement: active energy (kWh) with cumulative register
 Mounting: DIN-rail (standard distribution board profile)
 Communication: serial communication interface for integration with monitoring systems
 Form factor: compact single-module width suitable for panel installation
How to use
Install the meter on a standard DIN-rail inside the distribution board, ensuring proper phase and neutral connections according to local wiring regulations. Connect the incoming and outgoing conductors to the corresponding terminals, secure the meter mechanically, and verify tightness of all connections. Configure the communication parameters on the meter and on the receiving monitoring system to enable remote reading and data logging. After installation, perform an initial verification of measured values against a reference or known load to confirm correct wiring and calibration.
Usage recommendations
Place the meter in a dry, ventilated enclosure away from direct heat sources. Ensure that the installation and configuration are performed by qualified personnel following local electrical codes. For reliable communication, use shielded cabling where required and set matching communication parameters in the host system. Periodically inspect connections and seals and compare recorded energy values with expected consumption patterns to detect wiring or measurement issues early.
