Phase Failure Relay with Timer, 4-wire System 415VAC

Phase Failure Relay with Timer, 4-wire System 415VAC

SKU: NTR-301T

DIN rail mount, 4-wire system phase failure relays with independent over & under voltage control and adjustable time delay sequence (0.1 to 10 sec). SPCO relay output rated to 10 A @250 VAC. These are transformer based, thus it will ignore transients and harmonic distortions.

Phase failure relays from Foxtam UK with independent over and under voltage control as well as the additional adjustable sequence control.

An adjustable time delay of 0.1 to 10 sec (not true delay off), which is effective against voltage control and phase sequence. The units are transformers based and thus will ignore transients and harmonic distortions.

The SPCO output relay is energised when all three phases are connected and in sequence and within the set voltage limits. The output relay(s) will de-energise if one or more voltages between phases are under the value of the minimum set level or above the value of the maximum set level, less any set time delay.

The units will also de-energise on loss of a phase or incorrect sequence. Red LED indicates over and under voltage conditions. A green LED indicates output relay status. If both are illuminated this indicates a phase sequence error.
