HAGER EHZ003 eHZ tariefbeheer-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.
