The Tier AF Series Arc Flash Relay System reduces arc flash incident energy and boundaries in both Medium-Voltage and Low-Voltage electrical systems.
The Tier AF series is an externally installed control cabinet that uses both fiber optic sensors and current transformers (CTs) to immediately detect both light and current associated with an arc flash event and quickly activate a system disconnect.
