Improve worker safety and maximize

equipment uptime with Eaton’s Arc Flash Relay

Eaton’s Arc Flash Relay system helps improve worker safety

and maximize electrical assembly uptime by quickly

clearing arc flash events. Featuring factory-installed Arc

Flash Relay modules and sensors, the system is designed to

rapidly detect and clear even the most difficult forms of arc

flash events in low-voltage (LV) and medium-voltage (MV)

electrical assemblies. Arc faults are the most dangerous

type of fault in LV and MV switchgear. Eaton’s Arc Flash

Relay system reduces the arc energy by clearing the

current feeding the arc.

Features and benefits

• An innovative module system allows for simple integration

into electrical assemblies

• Sensitive light inputs detect low power phase to ground

arc faults

• The relay’s configurable setup offers optional system

selectivity, opening the circuit breaker closest to the arc flash

• Flexible module options allow installers to choose between

fiber optic loop cable and wired point sensors

• If the point sensor option is selected, the relay can be

factory wired and tested, reducing time and labor costs

Core features

• Suitable for use with any condensing type bushing found in transformers,

circuit breakers, shunt reactors, etc. With the InsulGard, it can be used to

detect partial discharge in systems above 38KV.

• All monitoring, necessary sensors, recording equipment and diagnostic

software are non-invasive, which eliminates downtime and power interruptions.

• Self-operating system saves on labor costs because staff can now spend

time solving problems rather than uncovering them.

• Remote monitoring services and on-site equipment evaluation provides

expertise when you need it.

• Display panel shows an output signal proportional to the relative change

in the bushings’ currents due to insulation deterioration, which means users

receive accurate information for both the power factor and capacitance of

the monitored bushing set.

• Multi-function LED is a different color for normal (green), warning (yellow),

and alarm (red), providing instant recognition of the severity of any problem.

• Parameters can be programmed at the panel or remotely through an optional

computer link-up, units are self-diagnosing, and users can pinpoint any

malfunction locally as well as remotely.

• Self-contained unit requires minimum resources and outage time. Comes

standard with NEMA 4 enclosure, diagnostic software, a three- or six-bushing

sensor set, and with an RS-485 Modbus RTU port that allows on-site

communication. The complete package means faster and easier installation.

• Uses the same sensor set to perform online periodic monitoring of partial

discharge (arcing or sparking). That information helps analyze root causes

of internal gassing or other discharge activity related to the winding insulation,

internal connections, bushings, or magnetic core iron.

Eaton’s BushingGard Predictive Diagnostic solution uses predictive

diagnostics to help users prevent malfunctions or breakdowns in

large power transformer bushing equipment. The self-operating

systems and remote monitoring services provide real-time detection

and allow users to work towards solving problems instead of finding

them. The bushing sensor requires minimum resources, accounts for

minimal outage time, allows for onsite communication, and results in

faster and easier installation.

• Uses the same sensor set to perform online periodic monitoring of partial

discharge (arcing or sparking). That information helps analyze root causes

of internal gassing or other discharge activity related to the winding insulation,

internal connections, bushings, or magnetic core iron.

• Highly sensitive instrumentation can detect PD signals as low as 20-30 pC

even in extremely noisy environments like those in substations or power plants,

which means accurate reports that allow for better decision making.

• Available with a commercial-grade modem for remote communication.

• Customized bushing sensors available with appropriate lead-time.

Increases Safety

• The QSCP uses the Bussmann series Compact Circuit Protector Base

(CCPB) for its branch circuit disconnect up to 100 amps and the Compact

Circuit Protector (CCP) for its 200 amp branch circuit disconnect. Both are

used with Bussmann series Class CF CUBEFuse fuses

• Both CCP and CCPB are disconnect rated to provide a means for load

isolation. Ampacity rejections at 15. 20. 30. 40. 50. 60. 70. 90. 100 and

200 A coincide with standard conductor sizes to help prevent overfusing

• Local open fuse indication on branch circuit device and optional indicating

CUBEFuse

• Lockout/tagout provision eases OSHA compliance

• Lock-On provision helps meet requirements for emergency circuits

• High fuse interrupting rating and up to 200 kA assembly SCCR ratings

easily exceed most available fault current levels to help ensure compliance

with NEC® 110.9 and 110.10. Current-limitation of a fused solution also

reduces arc-flash hazards and minimizes damage to equipment and circuits.

Flexible Configurations – Up to 600Vac/600 Amp/200kA SCCR,

or 125Vdc/600 Amp/100kA SCCR. 125Vdc rating applicable on

MLO panels only, up to 80A.

• 30. 60. 100. 200. 225. 400 and 600 A main ratings

• 125 Vdc rating ideal for utility and petro-chem control circuits or UPS

circuits

• 1 to 100 A fuse ratings to closely match loads

• Available in fused or non-fused main disconnect switch, or MLO (Main

Lug Only) configurations with a choice of 18. 30. 42. 60. 72 and 84 branch

positions, up to 200 A, in NEMA 1 or 3R enclosures to easily meet branch

or service panel installation needs

• Feed through lugs or fused loadside disconnect available

• Same size footprint as traditional circuit breaker panelboards

• 20” W x 5” D x various heights (depending on configuration), See data

sheet for specific dimensions/configurations

Addresses NEC® Selective Coordination Requirements

• This cULus Listed panelboard makes it easy to provide systems that

comply with NEC® Selective Coordination Requirements for Emergency,

Legally Required Standby, Healthcare Essential Electrical and Critical

Operation Power Systems (COPS) per 700.27. 701.18. 517.26 and 708.54

• Full fuse-system selective coordination is easy from source to branch.

Just follow published fuse selective coordination ratios – no need for

plotting time-current curves or expensive studies

The Quik-Spec Coordination Panelboard (QSCP) makes selective

coordination easy. Now available with up to 600 A mains and up

to 200 A branch disconnects as well as advanced and integrated

surge options.
