Power Quality & Management

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.
