The 250R Series is designed to protect against short duration high voltage fault currents (power cross or power induction surge) typically found in telecom applications (250Vrms). The series can be used to help telecom networking equipment meet the protection requirements specified in ITU K.20 and K.21.
0.08 – 0.18 hold current range, 60VDC operating voltage
250VAC interrupt rating
Fast time–to-trip
Binned and sorted narrow resistance ranges available
