The COUNTIS E3x is a modular energy meter displaying the energy and power consumed (kWh and kW) directly on its backlit LCD display. It is designed for three-phase load metering and is used for direct connections of up to 100 A.
COUNTIS E32, E34 and E36 are also MID-certified.

Conformity to standards

IEC 62053-21 class 1
- IEC 62053-31
- IEC 62053-11
- EN 50470-1
- EN 50470-3


RS485 (MODBUS or M-BUS) communication or pulse outputs

To enable power consumption to be reported remotely, COUNTIS E3x devices are equipped with either a pulse output or an RS485 communication output, on a MODBUS or M-BUS protocol.
As well as their reporting functions, COUNTIS E3x units with RS485 can be configured remotely and deliver multi-measurement readings.

Detection of connection errors

The device is protected against phase/neutral inversion and detects wiring errors. This simplifies the installation and commissioning, thereby reducing associated costs, and ensures that the device operates correctly.

B+D module MID-certified

COUNTIS E units comply with the MID directive to guarantee accuracy and reliability when metering, compulsory for energy billing applications. "Module B+D" certification guarantees that the design and manufacturing process of products are approved by an accredited laboratory.

Bi-directional metering (available only on the E33 and E35)

This function is for metering energy production or energy consumption.

Multi-measurement and load curve

Display of electrical values (I, U, V, P, Q, S, PF) and power curve over a 7 day period via communication.
