• 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.
