IMPROVE SAFETY AND RELIABILITY WITH INSTANT ARC-FLASH DETECTION OVER 13,000 LITTELFUSE ARC-FLASH RELAYS INSTALLED WORLDWIDE Littelfuse Arc-Flash Relays Fast Arc-Flash Detection Circuit breakers (CBs) or overcurrent protection devices (OCPDs) alone do not provide optimal protection for your personnel and equipment. The Littelfuse Arc-Flash Relays rapidly detect an arc flash and send a trip signal to interrupt power. PGR-8800 Arc-Flash Relay Control Power 110-240 VAC/VDC Control Power 14-48 VDC or Battery* Digital Inputs Outputs Trip Coil PC Connection PGA-LS10 Point Sensor Inputs PGA-LS20/PGA-LS30 Fiber-Optic Sensor Inputs CT Inputs *Backup battery not included Simple Plug & Play Installation and Maintenance The PGR-8800 and AF0500 Arc-Flash Relays and sensors are easily retrofitted into existing switchgear or pre-installed in new equipment with little or no configuration. Even elaborate systems only take minutes to configure using the relays’ built-in USB interface software, and the innovative digital inputs/outputs on the AF0500. g g g Improve sustainability and life of electrical equipment Lower the Hazard Risk Category (HRC) of the equipment Provide protection against equipment damage and potential injury to personnel g g g Easily installed without changes to existing layout Flexible sensor configuration for any application No additional software is required Installs up to 8X Faster than Competition! Installing a Littelfuse arc-flash relay can lower your HRC rating.

Littelfuse.com/ArcFlash 3 Littelfuse Arc-Flash Relays Superior and Robust Sensor Design PGA-LS10 Point Light Sensor ARC-FLASH RELAY Line-of-sight light sensor detects an arc as small as 3 kA in a 2-meter half-sphere radius. g Visual LED indication for “Ready” or “Tripped” state to assist with fault location g g PGA-LS20/PGA-LS30 g g 2.5m Up to 50 m cable Sensor can be installed up to 50 m (164 ft) away from relay; electrical cable can be cut and easily re-terminated in the field The 360° light sensor detects light throughout the entire length of the fiber. Ideal to protect bus bars, multiple compartment installations like motor control centers, or areas with many obstructions. g Visual LED indication for “Ready” or “Tripped” state to assist with fault location g Durable resin fiber material allows small bending radius (>5 cm) and greater flexibility without breaking 180˚ 2-meter Half-Sphere Sensor Viewing Angle Connect to Relay Robust sensor design can withstand a detected arc-flash event Fiber-Optic Light Sensor PGR-8800 SERIES ARC-FLASH RELAY 2m Light Sensor PGR-8800 SERIES Connect to Relay Black Shield (no light detection) Fiber-Optic Sensor 360˚ Light Detection PGA-LS20 (8 m/26.2 ft*) PGA-LS30 (18 m/59 ft*) * Distance of light-detecting fiber Receiver Up to 50 m cables Ready to install from the factory, no need to terminate in the field or polish as with glass fiber Fiber sensors can be installed in locations up to 50 m (164 ft) away from relay; electrical cable can be cut and easily re-terminated in the field Transmitter Sensor Placement Recommendations Generally, it is recommended to mount 1 or 2 sensors per cubicle to cover all horizontal and vertical bus bars, breaker compartments, drawers, and anywhere that there is potential for an arc fault. Threading a fiber-optic sensor through the cabinets and in areas where point-sensor coverage is uncertain results in complete coverage and an added level of protection. Even if policy is to only work on de-energized systems, all maintenance areas should be monitored for arc flash to prevent potential damage and additional cost.

Arc Flash Fiber-Optic Sensor Point Sensors Scenario with point sensor placement on the wall of each compartment. Arc detection area for each sensor is shown in green shade. In this case, both Point Sensor 1 and the Fiber-Optic Sensor detected the flash as it was within their viewing area (shown in orange). 4 Littelfuse.com/ArcFlash Application Example PGR-8800 Fiber-Optic Sensor Fiber-Optic Sensor Transmitter Receiver Control Power & Battery Back-up Point Sensor PGA-LS20 and PGA-LS30 Detects light 360° along the entire length of the exposed fiber.

Littelfuse.com/ArcFlash 5 Littelfuse Arc-Flash Relays Reliable Operation with Built-In Redundancies When you are entrusting a safety device to protect equipment from catastrophic damage, it is important to know that it will operate as expected. Littelfuse Arc-Flash Relays do this by having built-in redundancies and health monitors, making maintenance and installation tasks faster, more efficient and helping to minimize downtime. PGR-8800 Redundant Internal Trip Path ■■Two internal trip paths for added reliability—if the microprocessor trip path fails, the backup analog trip path will seamlessly take over, sending an alarm notification to operators Backup analog trip path initializes very quickly upon power up, ensuring protection is enabled while energizing the system when hazard risk is higher ■■ Health Monitoring ■■Continuously monitors connection to trip coil to ensure path is intact LED indication of sensors’ “Ready” or “Tripped” status on sensor and relay ■■ Sensors are durable enough to withstand a detected arc-flash event ■■ Reliable Light Detection ■■Two types of light sensors (point and fiber-optic) for different applications Adjustable light-level and wide-angle detection add flexibility ■■ Durable and flexible sensor design eliminates breakage and re-work ■■ Upstream Tripping ■■Ability to trip upstream device if the local breaker fails to clear the fault Optional Current Detection for Fault Verification ■■Avoid nuisance tripping with current-supervised arc-flash trips Phase Current Transformers for overcurrent detection ■■ Two user-defined definite-time overcurrent protection levels and times ■■ Tie Breaker Tripping ■■Ability to trip both incoming feeder and tie breaker when arc is detected in one section of a switchboard Affected part of the switchboard is isolated from the non-affected part ■■ Zone Tripping ■■Ability to trip 2 separate zones with 1 relay Sensor zone assignment through simple PC configuration and/or digital inputs and outputs ■■ 6 Littelfuse.com/ArcFlash AF0500 AF0500 Arc-Flash Relay Technical Specifications PGR-8800 Arc-Flash Relay Relay Part Nos.
