IMPROVE SAFETY AND RELIABILITY WITH INSTANT ARC-FLASH DETECTION
IMPROVE SAFETY AND RELIABILITY WITH INSTANT ARC-FLASH DETECTION
Fast Arc-Flash Detection in Less Than 1 ms
Minimize Damage. 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.
The Littelfuse Arc-Flash Relays use a 125-μs light-sampling scheme in combination with an ultra-fast IGBT output to be able to detect a developing arc flash and send a trip signal to a circuit breaker in milliseconds. Light instead of current is used to detect arc flashes.
Simple Plug & Play Installation and Maintenance
The Littelfuse 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 and AF0100
- Improve sustainability and life of electrical equipment
- Lower the PPE Category of the equipment
- Provide protection against equipment damage and potential injury to personnel or incident energy
- Easily installed without changes to existing layout
- Flexible sensor configuration for any application
- No additional software is required
PGR-8800 Application Example
Switchgear Protection
The PGR-8800 monitors each cabinet with a PGA-LS10 point sensor, providing arc-flash protection and fault location indication. The entire length of the back bus bar is monitored by a PGA-LS20 or PGA-LS30 fiber- optic sensor. The PGR-8800 uses current transformers to monitor the current, and trips the local “feeder” circuit breaker only when high amounts of light and current are present. The PGR-8800 is also configured to only trip the upstream “main” breaker if the local circuit breaker fails to open.
