• Industrial duty fuses with ceramic bodies.

FAST-ACTING

• The excellent current limiting characteristics of fast-acting

HRCI-J fuses limits damage to equipment and installations by

the thermal and magnetic energy associated with a large

short-circuit fault current.

200,000A I.R.

CSA C22.2 NO. 106 M92

BS88:2, IEC269:2

• Overload characteristics limit cable damage due to low over-

load currents.
