£149.10
The Carlo Gavazzi DWB01CM4810A is a reliable three-phase power factor monitoring relay designed to monitor motor load conditions and protect industrial equipment from abnormal operating states. As part of the advanced Carlo Gavazzi DWB01 monitoring relay series, it provides accurate power factor supervision for asynchronous motors and balanced three-phase loads in industrial automation systems.
This monitoring relay measures the actual load of electrical motors by monitoring the relationship between active and apparent power. The DWB01CM4810A helps detect underload and overload conditions through adjustable power factor limits, making it suitable for applications where reliable machine protection and process monitoring are required.
With a 380–480 V AC three-phase supply, a measuring range up to 10 A and a compact 45 mm DIN rail housing, the DWB01CM4810A is ideal for industrial control panels, motor protection systems and automation installations.
Power factor monitoring relays such as the Carlo Gavazzi DWB01CM4810A provide valuable information about motor loading and operating efficiency. By identifying changes in load conditions, they help prevent equipment damage and improve the reliability of automated machinery.
The DWB01 series is designed for automation engineers and electrical panel builders requiring compact and dependable load monitoring solutions. Its DIN rail format, adjustable settings and relay output allow straightforward integration into industrial control systems.
