| Description | Arc-Flash Relay; Light; 4; <1ms |
| Datasheet | Download Datasheet |
The Littelfuse Startco AF0500-00-CC is an arc-flash relay.
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. Sensors: 4. Sensor inputs: 4 light sensor inputs for PGA-LS10, PGA-LS20 and PGA-LS30 sensors. Trip time: <1ms.
Supply: Universal: 100 to 240 Vac (+10%, -15%) 50/60 Hz, 20 VA, 110 to 250 Vdc (+10%, -20%) 8 W; Low Voltage: 24 to 48 Vdc (+10%, -20%), 4 W.
Outputs: trip outputs: 2 IGBT switches; UL rating: 120/240 vac, 1800 VA, 0.75 A maximum continuous, 125/250 vdc, 138 VA, 0.75 A maximum continuous; Make/Carry 30 A for 0.2s; voltage rating 24 to 300 vac, 24 to 300 vdc; current rating 20 A for 2 s, 10 A for 5 s. Communications: Ethernet, 2 ports with internal Ethernet switch, Modbus® TCP; USB interface (configuration, event logs). Indication: front-panel and sensor LEDs indicate sensor health and which sensor detected an arc fault.
Mounting: surface, DIN (with optional D0050 adapter clips). Size: H 130 mm (5.1”); W 200 mm (7.9”); D 54 mm (2.1”). Operating temperature –40°C to +70°C (–40°F to 158°F). Conformal coating: conformally coated.
Approvals: UL Listed (UL508), CE, RCM, FCC, CSA.
