Tenso manufactures HRC (high-rupturing-capacity) NH knife-blade and BS 88 cylindrical fuse-links plus the bases that carry them, from NH00 to NH4, in gG and aM utilization categories. “HRC” means a sand-filled body that quenches the arc and clears very high fault currents without bursting — and the breaking-capacity rating (kA) must exceed the prospective short-circuit current at the point of installation. Choose gG for cables and general circuits; aM (with an overload relay) for motors. For power semiconductors, step up to semiconductor fuses; to mount and switch NH links, see fusible disconnect switches. Ratings are indicative; confirm against the datasheet and your installation’s fault level.

FAQ
HRC Fuses & Bases — questions buyers ask
What do NH00, NH1, NH2… mean?
They're the standard NH knife-blade fuse-link sizes, set by current rating and physical size — NH000 up through NH4 covers roughly 6 A to 1250 A.
What's the difference between gG and aM?
gG is general-purpose, full-range (cables and general circuits). aM is motor back-up, partial-range — it handles short circuits and inrush but gives no overload protection on its own, so it's used with an overload relay.
What breaking capacity do I need?
Enough to exceed the prospective short-circuit current at the point of installation. A fuse rated below the fault level can rupture under fault.
