039-26900-5040 / 253-PHDG under/above frequency monitor by Crompton

The Crompton Instruments 039-26900-5040 (253-PHDG) is an under/over frequency relay monitor designed by TE Connectivity. This unit features an input of 400 V AC and operates at a frequency of 50 Hz, corresponding to ANSI 81U/O standards. The frequency monitor is equipped with volt-free relay contacts. For operational configuration, the over-frequency function defaults to energize on trip, while the under-frequency function defaults to de-energize on trip. This industrial monitoring component provides reliable frequency protection for electrical systems requiring precise under and over frequency detection at 400V and 50Hz parameters.
