IQ-500

Protective Relays provide you with unique micro-processor-based devices that eliminate unnecessary trips, isolate faults, protect motors and provide system information to help you better manage your system.

  • Overload class is adjustable using DIP switches for 5, 10, 20, or 30 seconds, maximum trip times at six times rated current
  • Designed for 1000 V and less distribution systems
  • Class II ground current
  • Phase unbalance and phase loss
  • Manual or automatic reset (either a true manual or remote electrical reset) selectable
  • Form C (NO/NC) contact on output relay
  • Isolated alarm relay output contact
  • LED indication (bi-colored - red/green) for device status, including overload, phase unbalance, or ground current trip
  • Communications capability using IMPACC networkOverload (overcurrent) protection

The base relay can serve as the initial building block for a motor protection system by adding the IQ 500M Special Function Module. The module can address application related motor load functions with the additional features:

  • Underload protection
  • Long acceleration
  • Jam protection
  • Load control

The IQ 500 can provide a cost-effective alternative to conventional protective relays such as current relays, ground fault relays and phase loss or phase unbalance relays. Used with the PowerNet™ system, a low-cost, local area communication network, information such as current values, status, setpoint values, and cause of trip can be displayed remotely. The IQ 500 relay is ideal for a variety of industrial applications such as mining, timber, material handling, air conditioning compressors, wastewater treatment plants, and petrochemical industries.
