Description

GZ Three-Phase Solid State Relays with Logic Control

The GZ series consists of three-phase zero-crossing solid-state relays designed for control of resistive and inductive loads.
These integrated units are ideal for industrial applications requiring high power control and frequent switching, supporting loads up to 3 × 55A (AC51) at 400/480/600 Vac.
Control is via logic signal (Vdc), with LED indicators showing operational status. Each phase is managed by semiconductor components.
Robust construction, specialized manufacturing processes, and a durable case ensure excellent reliability and long-term service continuity.
All models include protection against overvoltage and junction overtemperature, with LED signals and optional solid-state alarm output.
Devices come with removable protective covers to prevent direct contact during wiring.
Optional accessories include heatsinks, thermostats, fans, fuses, and fuse holders.
Warning: GZ models must be used with an appropriate heatsink (sold separately). Installation must strictly follow the instructions in the installation notes.
