Littelfuse Arc Fault Relays
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
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.
