Why Choose the Carlo Gavazzi DUB02CT23 Voltage Monitoring Relay?
The Carlo Gavazzi DUB02CT23 is a precise and reliable single-phase AC voltage monitoring relay designed to protect electrical systems by detecting overvoltage and undervoltage conditions. As part of the advanced Carlo Gavazzi DUB02 monitoring relay series, it provides dependable voltage supervision for industrial automation, electrical control panels and machinery protection applications.
This monitoring relay continuously measures its own supply voltage and activates its relay output when the voltage moves outside the configured window limits. With true RMS measurement, programmable latching and inhibit functions, LED status indication and a compact DIN-rail housing, the DUB02CT23 provides flexible protection for industrial electrical systems.
With a 24–240 V AC/DC monitoring range, a self-powered design and a SPDT relay output, the DUB02CT23 is ideal for applications requiring reliable overvoltage and undervoltage monitoring in industrial control systems.
