1TPRB - Single-Phase Test Point Mounted Bolt Display FCI

Use SEL test point voltage reset fault indicators with remote tamperproof bold displays (1TPRB) on 200 and 600 A class underground distribution systems whose terminators have test points. The 1TPRB requires a 5 kV phase-to-ground minimum voltage to reset and remain ready to trip. Its remote bolt automatically resets when system voltage returns to normal
