Description
ARC FLASH RELAY
AF0500-00 is an arc-flash relay with a supply voltage ac of 100–240.
Description
The AF0500 is a microprocessor-based arc-flash relay that
limits arc-fault damage by detecting the light from an arc flash
and rapidly tripping the feeder breaker. The unit is well suited
for switchgear, transformer and power converter applications.
Sensors, inputs, and connections are health monitored
to ensure fail-safe operation. A secondary solid-state trip
circuit provides a redundant trip path. A USB port is used for
configuration and access to event logs.
AF0500 includes an Ethernet interface and supports Modbus®
TCP communication. Zone tripping, upstream breaker tripping
and tie breaker tripping applications can be easily configured.
A number of control inputs allows interconnection of multiple
AF0500 units to form a system.
