Speed	As fast as 2 ms operating time
Flexibility	• Easy adaptation to any switchgear and trip scheme • Variety of arc sensors available • Long distance possible between units • Practically an unlimited number of units can be interconnected in one system
Reliability	• Standard copper wire for communication between units • Superior isolation levels for external disturbances - tested at the highest EMC classes • Full internal monitoring of all system components and interconnections
Typical applications	• Low voltage switchgear/switchboards • Medium voltage switchgear • Low/medium voltage motor control

FEATURES

• An innovative module system allows for simple integration into electrical assemblies
• Sensitive light inputs detect low power phase to ground arc faults
• The relay’s configurable setup offers optional system selectivity, opening the circuit breaker closest to the arc flash
• Flexible module options allow installers to choose between fiber optic loop cable and wired point sensors
• If the point sensor option is selected, the relay can be wired and tested, reducing time and labor costs
