The IQ Energy Sentinel is the latest addition to the Cutler-Hammer line of IQ Metering devices, which includes the IQ Data, IQ Generator, IQ Data Plus II, IQ Data Plus II HV, and the IQ Analyzer. These solid-state products provide centralized alternatives to individually mounted ammeters, voltmeters, frequency meters, watt-hour meters, and more. All are easily retrofitted into existing systems, and communicate over the Cutler-Hammer IMPACC System, a local area network designed specifically for use in electrical distribution systems.

IQ Energy Sentinel

The IQ Energy Sentinel is a highly accurate, microprocessor-based submeter designed to monitor power and energy. It represents an alternative to installing separate watt meters, watt-hour meters, and watt demand meters.

Key advantages include unmatched savings in space, lower installation costs, and the capability to communicate data readings in a variety of ways.

IQ Energy Sentinels with built-in CTs and communications have the added benefit of greater overall system accuracy. Conventional metering often is less accurate since external CTs and separate transducers may each have inaccuracies of 1% or more.

The IQ Energy Sentinel provides a unique and cost-effective method to implement energy submetering at lower levels in the distribution system.

Submetering application examples for the IQ Energy Sentinel include energy monitoring and demand management, product cost analysis, process/machine tool efficiency and productivity improvement, and energy cost allocation or tenant billing for commercial, industrial, recreational, and residential facilities.

Note: For customer billing applications, consult local utility for metering requirements.

Commercial applications include energy cost allocation within convention halls, office buildings, shopping malls, hospitals, warehouses, and storage facilities.

Industrial applications include departmental billing and process/assembly line energy cost analysis. IQ Energy Sentinels may be substituted for watt transducers when monitoring machine tool and equipment performance within plants.

Recreational facilities include sports arenas, camping grounds, trailer parks, and marinas.

Multitenant residential buildings and apartment buildings can be submetered as well.

The IQ Energy Sentinel may be applied on three-phase (3-wire or 4-wire) systems, as well as on single-phase (3-wire) systems.

IQ Energy Sentinels may be applied on either 50 or 60 Hz systems.

Breaker Mount Applications

New Equipment:
Designed for mounting on Cutler-Hammer Series C Circuit Breakers utilized in Cutler-Hammer assemblies such as:

• Pow-R-Line 4 Panelboards – feeder circuits
• Pow-R-Line C Switchboards – feeder circuits
• Series 2100 Motor Control Centers and Enclosed Control with circuit breaker disconnects – starter or feeder circuits
• Enclosed Starters
• Enclosed Circuit Breakers
• Pow-R-Way II Bus Plugs with circuit breaker disconnects

Retrofitting:
The space-saving design characteristics of the breaker mount IQ Energy Sentinels allow them to be added to existing Series C Circuit Breakers at any time...often with no additional space or modifications required.

Or they may be installed when upgrading to Series C from older circuit breakers...often with no additional space or modifications required.

Universal Mount Applications

The universal mount IQ Energy Sentinel with internal CTs may be utilized wherever breaker mounting is not feasible or possible. In particular, they may be used on any disconnect up to 400 amps.

The universal mount IQ Energy Sentinel for external CTs may be utilized for monitoring loads larger than 400 amps, on power cable sizes larger than 500 MCM, or on circuits containing more than one conductor per phase.

Cutler-Hammer Series C Breaker Mount
The breaker mount IQ Energy Sentinel installs in less than 10 minutes on the load side of a Cutler-Hammer Series C F-frame (150 amp), J-frame (250 amp), or K-frame (400 amp) circuit breaker.

Universal Mount With Internal CTs
The universal mount IQ Energy Sentinel with internal CTs may be panel mounted or DIN-rail mounted on disconnects or other circuits up to 400 amps. A pull-apart terminal block is provided on the device for connection of the system voltage reference wiring.

Note: The location of the ground/neutral connection differs on breaker mount IQ Energy Sentinels from the location of the ground/neutral connection on universal mount IQ Energy Sentinels. Incorrect wiring to the ground/neutral and communications connections may result in accurracy and communication errors.

Universal Mount for External CTs
The universal mount IQ Energy Sentinel for external CTs may be panel-mounted or DIN-rail mounted on circuits up to 4000 amps.

A pull-apart terminal block is provided on the device for connection of the system voltage reference wiring, as well as another terminal block, for connection to the user's existing 5-amp secondary CTs, which may range in standard ratios from 25:5 up to 4000:5.

If the device will be disconnected without interruption of the monitored load, the use of a CT shorting block is advised.
