Multifunction voltage monitoring relay in 3P with LCD display

Start of sales: March 2021

Multifunction and in many ways universal monitoring relay which protects devices and equipment connected to a 3-phase network.

3-wire or 4-wire connection (with or without neutral).
Optionally monitors high and low voltage & frequency in 3-phase circuits.
Allows monitoring of failure, sequence and phase asymmetry incl. neutral failure (only for 4-wire connection).
The product is powered by a monitored voltage.
Both output contacts can be set individually.
Measures the true RMS value of True RMS.
Optional setting of output contact response delay and measured error condition incl. Possibility of delayed response of the output contact after power supply connection.
Possibility of manual or automatic (default setting) transition from error state (memory).
Optional closing or opening of the output contact when measuring an error condition (Fail Safe/Non Fail Safe).
Password protection against unauthorized changes to settings.
Digital backlit display with the ability to monitor the current state of the network incl. possible failures.
The last fi ve error states are stored in a backed uphistory that is possible to view
Sealable transparent cover for display and controls.
