Why Choose the Carlo Gavazzi PUB02CT23 Monitoring Relay?
The Carlo Gavazzi PUB02CT23 is a compact and reliable single-phase AC over and undervoltage monitoring relay designed for electrical protection and industrial automation applications. As part of the Carlo Gavazzi PUB02 monitoring relay series, it provides accurate true RMS voltage monitoring by supervising its own power supply and switching a relay output when voltage levels move outside configured limits.
This monitoring relay provides flexible voltage supervision with selectable nominal voltage ranges, adjustable upper and lower thresholds, adjustable delay functions and programmable operating modes. The PUB02CT23 is designed for dependable integration into industrial control panels where protection against abnormal voltage conditions is required.
With selectable 24/115/230 V AC nominal voltage ranges, a SPDT relay output and a 36 mm plug-in housing, the PUB02CT23 is suitable for machinery, automation systems and electrical installations requiring reliable overvoltage and undervoltage monitoring.
