            The JDTFUSE A250 Series is designed to protectagainst 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 theprotection requirements specified in ITU K.20 and K.21.
