  • Models Available up to

480 VAC

EQUIPMENT AGAINST:

  • Phase Loss
  • Under Voltage
  • Phase Unbalance LOCK SHAFT ADJUSTMENT FOR:
  • Phase Unbalanced Percent
  • Under Voltage Drop Out
  • Automatic Reset
  • Delta or Wye Systems DIMENSIONS (INCHES) The SLE Series is designed to protect 3-phase equipment against PHASE UNBALANCE, PHASE LOSS, and UNDER VOLTAGE. With normal operating voltage present on all three phases, the internal relay will energize (PICK-UP). When a phase loss occurs or the voltages fall outside the preset unbalance or under voltage settings, the internal relay will de-energize (DROP-OUT). The relay automatically resets when the line conditions return to normal. Both Delta and Wye systems may be monitored. In Wye Systems, connections to neutral are not required. NOTE: When a phase is lost while the motor is running, a condition known as regeneration occurs where a voltage is induced into the open phase nearly equal in magnitude to the normal phase-to-phase voltage. The SLE series is designed to detect this condition when properly adjusted. The SLE Series is UL Listed under UL File Number E55826 OPERATION WIRING SPECIFICATIONS OPERATING See Table Below VOLTAGE TRANSIENT 1000 Volts For 8 mSEC PROTECTION RESET Automatic PHASE UNBALANCE 2% to 10%, Adjustable RANGE INDICATORS LED Glows When All Conditions Are Normal RESPONSE TIMES Operate 60 Milliseconds MODELS UP TO Release 0.5 Seconds
