Fuses & Fuse Links NZ

Ideal carries fuses and fuse links from GE UK, RS Components, Ferraz, Transnet and more for low-voltage distribution, control circuits and switchboards, with current ratings and breaking capacities across HRC, cylindrical, blade and D-system types held in stock through our 37 nationwide stores.

Selecting the Correct Fuse Link 

Fuse types and where each is used

HRC (high rupturing capacity) fuse links handle higher fault currents and suit distribution boards and switchboards. Cylindrical fuses suit control, instrumentation and general low voltage circuits, while blade fuses suit automotive and low voltage DC applications.

Current rating and breaking capacity

Replace a fuse link with one of the same current rating and breaking capacity as the original. Fitting a higher rated fuse link than the circuit was designed for removes the protection the circuit depends on.

Carrier and mounting compatibility

Fuse links are built to specific carrier types and centre-fixing dimensions, including common sizes such as NH2 and NH3. Check your existing fuse carrier or holder before ordering so the replacement seats correctly.

Keeping spares on hand

A blown fuse link often means unplanned downtime, so many commercial customers keep common ratings in stock rather than ordering on demand. Contact our team to set up regular supply for critical ratings, or see our earthing and surge and lightning protection ranges for other circuit protection needs.

Fuses & Fuse Links FAQs

What is the difference between an HRC fuse and a cylindrical fuse link?

HRC (high rupturing capacity) fuse links interrupt higher fault currents safely and are used in distribution boards and industrial switchboards. Cylindrical fuses generally suit lower current control and instrumentation circuits; match the fuse type to the application it was specified for.

How do I know what fuse link to use as a replacement?

Check the current rating, voltage rating and physical dimensions marked on the original fuse link or nameplate, and replace like for like. Contact your local branch if the marking is unclear.

Will this fuse link fit my existing fuse carrier?

Fuse links are made to specific carrier and centre-fixing dimensions, so check compatibility before ordering. See our fuse carrier range to confirm or replace the holder itself.

Can a fuse link be replaced with a circuit breaker instead?

In some applications, a circuit breaker can replace fuse protection, though this depends on switchboard design and fault levels, so any change should be assessed by a qualified electrician rather than swapped without review. Browse our circuit breaker range if reviewing options for a new installation.
