AUXILIARY SUPPLY BURDEN
(At 110V DC)
Monitoring mode: Less than 4W
Arc fault detected: Less than 10W for 2s
AUXILIARY SUPPLY
20 - 60V DC

6 – 150V DC
OPERATE TIME
Arc fault trip contacts guaranteed to pick up in less than 10ms
including bounce. Typical operate time is 7ms.
CRO trace showing nominal operation time of the trip contacts at
7ms. First contact touch at 6.25ms and fully closed by 7.25ms.
Operation in <10ms is considered acceptable as current check
relay operate time is ~15ms.
ARC SENSOR INPUTS
Two or three independent arc sensor inputs type 1S30 or similar.
Figure 20: 1S30 Arc Fault Sensor (Refer 1S30 Technical Bulletin)
MINIMUM ARC DURATION
The minimum arc “flash” duration required to guarantee operation
of the output contacts is 1.25ms.
TRIP CONTACT RESET TIME
Once operated the trip output contacts reset as per the
configuration switch 4 setting.
MANUAL RESET
Press front button or interrupt power supply to reset LED’s.
