Current monitoring relay PRI-32

  • THE CURRENT TRANSFORMER RELAY, WHICH SENSES THE CURRENT THROUGH THE PASSING WIRE, IS USED TO MONITOR THE HEATING RODS IN THE SWITCHES, THE HEATING CABLES, THE CURRENT FLOW INDICATION, AND THE MONITORING OF SINGLE-PHASE MOTORS.
  • IN SUITABLE WIRING, IT CAN ACT AS A POWER CUTTER FOR THE POWER RESERVE AND ALLOW YOU TO REDUCE THE SIZE OF THE MAIN CIRCUIT BREAKER (AND THUS THE AMOUNT OF PAYMENT FOR THIS CIRCUIT BREAKER).
  • THE DESIGN REDUCES THE THERMAL STRESS OF THE PRODUCT COMPARED TO THE CONVENTIONAL SOLUTION WITH THE BUILT-IN SHUNT, INCREASES THE CURRENT RANGE UP TO 20A AND GALVANICALLY SEPARATES THE MEASURED CIRCUIT.
  • SUPPLY FROM MONITORED VOLTAGE.
  • IN CONJUNCTION WITH THE SUPPLIED CURRENT TRANSFORMERS, THE BASIC CURRENT RANGES CAN BE EXPANDED UP TO 600A, INCREASING THE RANGE OF USE.

• Current transformer is a part of the product. Inside this transformer
there is a wire which senses the volume of fl owing current.
• This construction reduces thermal stress of product when compared
with conventional solutions with inbuilt shunt, and increases current
range up to 20 Amps, and galvanically separates monitored circuit.
• For heating bars in sliding rails, heating cables, indication of current
fl ow, controlling of 1-phase motor consumption…
• Universal supply AC 24 – 240 V and DC 24 V.
• Supply is galvanically separated from measuring current.
• Current exceeding – current fl owing through monitored wire must not
exceed 100 A.
• Output contact: 1x changeover / SPDT 8 A.
• Clamp terminals.
• 1-phase, 1-MODULE, DIN rail mounting.
