Download data sheet

An attractive modern designed range of combined phase failure and sequence relays in a din rail mounted modular style housing of 1.5 modules width (27mm). Utilising transformer technology the units are available in either 3 wire or 4 wire versions, the 4 wire version also trips on loss of the Neutral. Both types are available with either a SPCO or DPCO output. On power up with all three phases present (plus the Neutral if applicable) and in the correct sequence the output relay/s will energise, the green and red LED’s also illuminate. On loss of a phase, (or Neutral 4 wire versions), drop in voltage below Umin levels, or incorrect phase sequencing the output relay/s after a fixed time delay of 0.5 secs will drop out and the red LED will be extinguished. A green supply on LED only illuminated means that there is a supply to the unit but there is a supply fault of phase loss, under volts, or sequence. All terminal details and information along with the CE mark is clearly marked on the sides of the housing.
