This protection Under & Over Voltage Relay 253-PVE can be used to protect against:

  • Under voltage
  • Over voltage

Applications:

  • Gensets: to monitor correct operation of the A VR (Automatic Voltage Regulator) & excitation system & the engine speed controller (Governor)
  • Motors: Some electric motors are voltage sensitive, & can overheat & burn out when operated at low voltages. Synchronous motors rotate at speed proportional to line frequency. Use these relays to ensure correct running speed.
  • UPS supplies: when the main A.C. supply falls outside the acceptable operating voltage window, the relays can initiate a change over to an alternate or standby supply.

    Product Details:
    Minimum Order Quantity1 Unit
    Frequency Range 50/60 Hz
    Rated current1A or 5A
    Output Relay 2 Change-over contacts
    Voltage TypeAC

    The Sensitive Earth Fault Current Relay IRI1-ES from C&S detects high impedance earth faults with very small currents. Conventional earth fault relays (IDMT) do not provide the required sensitivity. For this application, the IRI1-ES is the optimal solution.

    Characteristics and Features:

    • Static protective device
    • Earth fault detection with core balance C.T. or in Holmgren circuit
    • Low pass filter for suppression of harmonics
    • Coding for the self-holding function or automatic reset of the LED’s and trip relays
    • Extremely large setting range for current reaction value with fine grading
    • Wide range of operation of the supply voltage (AC/DC)

    We provide products service from 18 months to 5 years.
