£72.40
The Carlo Gavazzi DPB51CM44B006 is a compact and reliable three-phase voltage monitoring relay designed to protect electrical equipment by continuously supervising phase conditions in industrial automation and control systems. As part of the Carlo Gavazzi DPB51 monitoring relay series, it provides dependable monitoring of three-phase and three-phase plus neutral supplies for applications requiring improved equipment protection and operational reliability.
This monitoring relay detects abnormal electrical conditions including phase loss, phase sequence faults, overvoltage and undervoltage conditions. The self-powered design measures the monitored mains supply directly, while the compact DIN-rail housing enables straightforward installation inside electrical control panels and industrial switchgear.
With a 208–480 V AC three-phase monitoring range and neutral monitoring capability, the DPB51CM44B006 is suitable for industrial applications where reliable phase supervision and fault detection are required.
Three-phase monitoring relays continuously supervise electrical supplies to identify phase faults and abnormal voltage conditions before they cause equipment downtime or damage. The Carlo Gavazzi DPB51CM44B006 provides dependable protection for motors, machinery and industrial electrical installations.
The DPB51 series is designed for automation engineers and panel builders requiring compact monitoring solutions. Its integrated voltage monitoring functions, relay output and DIN-rail format allow efficient installation within modern industrial control cabinets.
