Fuse Holders

A fuse holder is a carrier that holds a cylindrical cartridge fuse, connects it into the circuit and makes the fuse easier to replace. It is used in panels to protect control, measurement and motor circuits, for DC string fuses in photovoltaic systems, and at the supply inputs of electronic devices. This page includes ABB's E 90 series fuse holders and fused disconnectors, the E 90 PV solar fuse holder, Schneider Electric TeSys DF series 1-pole and 3-pole models for 10x38, 14x51 and 22x58 mm fuses, and Konsan's 5x20 and 6x30 mm fuse holders; ABB E 9F series cartridge fuses are in the same list. Choose the holder by the size, rated current and voltage of the fuse to be used, the number of poles, and whether the circuit is AC or DC. The rated current of the holder indicates the largest fuse it can accept; the level of protection is determined by the rated current and duty class of the installed fuse. A fuse holder should not be confused with a fuse box: the holder carries a cartridge fuse, while a fuse box is the enclosure in which miniature circuit breakers are lined up.

How to choose Fuse Holders

A fuse holder is a carrier that holds a cylindrical cartridge fuse, connects it into the circuit and makes the fuse easier to replace. It is used in panels to protect control, measurement and motor circuits, for DC string fuses in photovoltaic systems, and at the supply inputs of electronic devices.

  • Clarify whether the task is connection, cable routing, enclosure distribution or termination.
  • Match dimensions, thread standard, conductor cross-section and IP rating with the cable and panel.
  • Choose housing material and pack quantity according to the mounting environment.
