The Carlo Gavazzi PUB03CW24 is a compact and reliable single-phase AC/DC voltage monitoring relay designed for overvoltage and undervoltage monitoring in industrial automation and electrical protection systems. As part of the Carlo Gavazzi PUB03 monitoring relay series, it provides dependable voltage supervision by monitoring its own power supply and switching a relay output when voltage conditions exceed configured limits.
This monitoring relay provides flexible voltage protection with selectable monitoring ranges, adjustable alarm delay and configurable operating functions. The PUB03CW24 is designed for industrial control panels where accurate voltage monitoring and reliable relay switching are required.
With a 24/48/115/240 V AC/DC nominal voltage range, a SPDT relay output and a 36 mm plug-in housing, the PUB03CW24 is suitable for machinery, automation systems and electrical installations requiring dependable overvoltage and undervoltage monitoring.
Voltage monitoring relays such as the Carlo Gavazzi PUB03CW24 continuously supervise electrical supply conditions and provide a switching output when voltage levels move outside configured limits. This enables control systems to trigger alarms, disconnect equipment or initiate protective actions during abnormal operating conditions.
The PUB03 series is designed for industrial automation engineers and electrical installers requiring dependable voltage protection with straightforward installation. Its compact plug-in design, relay output and adjustable delay function allow easy integration into industrial control systems.
