Trailing Cable Protection

Trailing cable protection relays
Trailing cable protection relays help prevent ground faults and damage from hazardous voltages. The relays also continuously monitor the integrity of ground conductors. Different versions produced by Littelfuse are specifically engineered for use with either underground mining equipment or with fixed cranes or portable conveyors.
  • Alternating current supply voltage ratings from 120 V ac and 240 V ac
  • Operate at between 50 Hz and 60 Hz
  • Direct current supply voltage ratings from 24/48 V dc or 120/240 V dc
  • Adjustable trip current settings from 500 mA to 12.5 A
  • Adjustable trip time delay between 100 ms and 2.5 s
  • Meet CSA standards
  • UL Recognized and UL Listed
  • Available with normally open (Form A), normally closed (Form B), or combination normally open–normally closed (Form C) contacts
  • Fail safe ground check circuits
  • Conformal coatings protect internal circuits from corrosion
