AR360 Fault Indicators provide ultrabright flashing LED displays with 360 degrees of visibility. A distinctive "rotational" flash sequence enhances fault display location. Advanced microprocessor-based technology senses and measures load and detects faults on lightly loaded circuits with as little as 50 A of fault current. The AR360 steps up its trip threshold as the load increases to coordinate with the load. Permanent and momentary faults are identified separately through the use of red and amber LEDs and flash patterns. The AR360 identifies momentary faults with flashing amber LEDs. Permanent faults are indicated by a combination of alternating red and amber LEDs.
AR360 Fault Indicators are quick and easy to install with one hot stick. There are no clamps to disassemble. No extra hardware is needed. With AR360 Fault Indicators, detect momentary faults before they become outages and speed restoration after permanent faults.
Overhead Fault Location—Apply AR360 or AR-OH Overhead AutoRANGERs across your entire overhead system as an economical solution to reduce fault-finding time and improve reliability metrics. The AutoRANGER logic automatically selects the best trip threshold based on sampled load current and reduces effort of coordinating FCIs with various protection schemes. The AR360’s bright LED display provides higher visibility fault indication, day or night.
Momentary Fault Detection—Improve system reliability by tracking down momentary faults before they become permanent outages. The AR360 and AR-OH are equipped with simple-to-interpret displays that provide distinct flash patterns for both permanent and self-clearing faults.
Distribution Circuit Reliability Improvement—Deploy the AR360 on distribution circuits up to 34.5 kV.
