Description
ARC-FLASH RELAY UNIVERSAL SUPPLY
The AF0100 series arc-flash relay is a cost-effective, microprocessor-based protection relay that limits arc-flash damage
by using light sensors to rapidly detect an arc and then trip a circuit breaker. Any combination of point and fiber-optic
sensors can be connected to the relay to provide maximum protection. The AF0100 accepts PGA-LS10 point sensors and
PGA-LS20/PGA-LS30 fiber-optic sensors. These sensors are designed with a wide detection angle and provide the correct
sensitivity for an arc flash. LEDs on the relay and on the sensors indicate sensor health and which sensor(s) detected an
arc fault. Sensors, inputs, and trip-coil voltage are monitored to ensure fail-safe operation. A solid-state redundant trip circuit
provides an internal fail-safe mechanism and fast arc-flash response during power up.
The AF0100 unit comes with two isolated Form-C contacts for use in applications where multiple devices require tripping.
This is especially useful for generator applications where the generator and breaker need to be tripped in case of an arc
flash. The relay’s compact size and DIN-rail or surface-mountable features make it ideal for equipment manufacturers
