Item # LPC 10560-51

Heavy duty, 3 electrode gas tube arrester with fail safe open mechanism. Mounting on standard AAR 2 3/8” binding post terminals. For 0-30 VDC (0-24 VAC). The arrester is connected across the lines; protection provided each line to ground and line to line. Bipolar operation.

1. Nominal breakdown voltage 90 VDC line to ground; 150 VDC line to line. Let-through voltage (after initial microseconds) at 30V regardless of surge current amplitude or duration. Insulation resistance 1000 megaohms minimum.
2. Surge current rating maximum : 75 KA, for 8/20 µs; 5 KA for 10/1000 µs
   Life (minimum)
   • 10 KA 8/20 µs 200 operations
   • 25 KA 8/20 µs 50
   • 50 KA 8/20 µs 20
   • 75 KA 8/20 µs 2
   • 500 A 10/1000 µs 3000
   • 1 KA 10/1000 µs 500
   • 3 KA 10/1000 µs 50
   • 5 KA 10/1000 µs 2
3. End of Life
   1. Fail safe open by spring action pulling the gas tube out of internal connections. Visual inspection through transparent enclosure.
   2. Broken gas tube ceramic, visual inspection.
   3. High breakdown voltage.
   4. Insulation resistance below 10K ohms. Measurable with ohmmeter.
