Devices provide critical protection against phase loss and improper phase sequence. Model DPB52 also provides protection against under- and over-voltage. With a low profile DIN housing and 17.5 mm width, the monitoring relays can be installed in industrial cabinets as well as in electrical distribution NORM panels. A built-in switch-mode power supply allows DPA52 and DPB52 to filter and minimize harmonic distortions. This can help prevent devices from overheating and avoid failures and false alarms that could lead to unexpected machine downtime. The three-phase monitoring relays offer protection against disturbances and transients.
