£116.99
The Carlo Gavazzi DPA53CM48 is a compact and reliable three-phase voltage monitoring relay designed to protect electrical systems by monitoring phase loss, phase sequence and undervoltage conditions. As part of the Carlo Gavazzi DPA53 monitoring relay series, it provides dependable protection for industrial motors, machinery and automation equipment requiring accurate three-phase supply monitoring.
This monitoring relay continuously checks three-phase supply conditions and helps prevent equipment faults caused by missing phases, incorrect phase rotation and insufficient supply voltage. Its mini DIN rail mounting design, adjustable undervoltage monitoring and regenerated voltage detection capability make it suitable for industrial control panels and electrical protection systems.
With a 380–480 V AC three-phase monitoring range, a SPDT relay output and a compact 17.5 mm DIN rail housing, the Carlo Gavazzi DPA53CM48 provides a practical solution for phase monitoring applications in industrial automation and motor protection systems.
Phase monitoring relays such as the Carlo Gavazzi DPA53CM48 help protect motors and industrial equipment by identifying abnormal three-phase supply conditions before they cause operational problems. Monitoring phase sequence, phase loss and undervoltage conditions helps improve system reliability and reduce the risk of equipment damage.
The DPA53CM48 is designed for industrial automation engineers and panel builders requiring dependable electrical monitoring in machinery, motor control and process systems. Its compact 17.5 mm housing makes it particularly suitable for installations where control panel space is limited.
