HAGER EHZ003 eHZ Tariff Management Set (EHZ003)

The HAGER EHZ003 is an eHZ tariff management control unit that enables load control based on signals from electronic household meters (eHZ). With two potential-free relay outputs, each rated for 16 A (AC-1), it allows switching of loads according to tariff signals, supporting demand-side management in residential and commercial installations.

Overview

Designed for DIN rail mounting, the EHZ003 occupies 4 module units (TE) and operates on 230 V AC at 50/60 Hz. It receives input via an S0 interface from the eHZ meter, providing a reliable method for tariff-based load switching. The unit features screw terminals for secure connections and a thermoplastic housing for durability.
