£149.10
The Carlo Gavazzi DWB03CM4810A is a compact and reliable three-phase active power direction monitoring relay designed for monitoring electrical power conditions in industrial automation, energy management and motor control applications. As part of the Carlo Gavazzi DWB03 monitoring relay series, it provides accurate supervision of active power and power direction to help protect and optimise industrial electrical systems.
This monitoring relay measures three-phase electrical power conditions and provides a relay output when configured power direction or active power limits are detected. The DWB03CM4810A is suitable for applications requiring monitoring of power flow, abnormal load conditions and electrical system performance.
With a 380–480 V AC supply, measurement capability up to 10 A or via compatible MI current transformers, an SPDT relay output and a compact 45 mm DIN-rail housing, the DWB03CM4810A provides a flexible solution for industrial power monitoring applications.
Power monitoring relays such as the Carlo Gavazzi DWB03CM4810A help engineers supervise electrical performance by detecting abnormal power conditions and monitoring active power flow direction. This supports improved equipment protection, energy management and fault detection.
The DWB03 series is designed for automation engineers, panel builders and energy management specialists requiring compact DIN-rail monitoring solutions with dependable relay-based control outputs.
