| Datasheet | Download Datasheet |
The Littelfuse Startco AF0100-10-CC is an arc-flash relay with a 24–48 V dc supply.
It watches switchgear, motor control centres and panelboards for the light of an arcing fault and trips the upstream breaker within milliseconds, limiting the incident energy an arc flash can release. Detection: light; sensitivity 10–25 klux programmable. Sensors: 2 (dual sensor inputs). Sensor inputs: PGA-LS10 point sensors and PGA-LS20/PGA-LS30 fiber-optic sensors, any combination. Trip time: 5 ms (typical).
Outputs: trip, error relays: Form C, 250 V ac/30 V dc, 6 A resistive. Communications: USB interface (configuration); discrete wire networking with other AF0100 or AF0500 units. Indication: LED trip and sensor status indication on the relay and sensors; unit health indication.
Mounting: surface, DIN rail. Size: H 90 mm (3.5”); W 128 mm (5.0”); D 60 mm (2.4”). Operating temperature -40 °C to +70 °C (-40 °F to 158 °F).
