Description:
HRCI-J fast-acting fuses are industrial duty fuses with the excellent current-limiting characteristics of fast-acting HRCI-J fuses to limit damage to equipment and installations by the thermal and magnetic energy associated with a large short-circuit fault current.
Overload characteristics limit cable damage due to low overload currents.

Construction: Ceramic body fuse.
Ratings:
Volts:  600Vac (or less), 250Vdc
Amps:  1-600A
IR:  200kA

Agency Information: CSA C22.2 No. 106 M92; Designed to BS 88:2, IEC 60269-2.
