SEL-AR360 and SEL-AR
Overhead AutoRANGER Fault Indicators
The SEL-AR360 and SEL-AR are self-adjusting fault indicators for overhead lines. They automatically select trip thresholds based on sampled load current and improve system reliability and restoration speed by indicating momentary faults before they become permanent outages. The indicators separately identify permanent and momentary faults using red and amber LEDs and flash patterns. You can apply the SEL-AR360 on distribution systems up to 34.5 kV and the SEL-AR on systems up to 69 kV.
The SEL-AR360 and SEL-AR are quick and easy to install with one hot stick. There are no clamps to disassemble. No extra hardware is needed.
Starting At
$216Overhead Fault Location—Apply SEL-AR360 or SEL-AR indicators across your entire overhead system as a single 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 the effort of coordinating fault indicators with various protection schemes. The bright LED display provides high-visibility fault indication, day or night.
Momentary Fault Detection—Improve system reliability by tracking down momentary faults before they become permanent outages. The SEL-AR360 and SEL-AR are equipped with simple-to-interpret displays that provide distinct flash patterns for permanent and momentary faults.
Distribution Circuit Reliability Improvement—Deploy the SEL-AR360 on distribution circuits up to 34.5 kV and the SEL-AR on distribution circuits up to 69 kV.

Details
- Self-adjusting trip thresholds adjust based on the load current and eliminate the need to specify a trip threshold. This feature reduces engineering time and inventory by allowing you to use one device model across your entire system.
- Distinct momentary and permanent fault indications help you locate permanent and momentary faults.
- Battery-saving technology maximizes product and battery life with more than 2,500 flash-hours for the SEL-AR and more than 1,800 flash-hours for the SEL-AR360.
- An intelligent energy-saving LED display provides the appropriate level of intensity for ambient lighting conditions.
- Patented Ramp-Down Restraint feature prevents false activation after extended circuit lockout and provides trip-threshold memory.
- Rugged construction ensures a long product life.
- Installation is quick and simple.
- Installs with a single hot stick—no extra clamps or screws.
- Requires zero maintenance.
- Allows testing, activation, and manual clearing with the CRSRTT tool.
Some configurations, such as those with an LED or timed-reset feature, may contain a battery. For configurations with a battery, please see the lithium metal battery warning.
