ECL triggered by excessive voltage or current

BOURNS TBU PL-Series SLIC Transient Blocking Unit (TBU) circuit protection devices protect telecommunications applications from surges with an electronic current limiter. Device provides fast overcurrent protection combined with SLIC battery voltage tracking triggered protection. Combined with additional overvoltage protectors, device protects against very high surge levels and meets telecom 500A Telcordia GR-1089 intrabuilding and 6kV/150A ITU-T standards.
