Factory quote coordination

fuse holder

Industrial Fuse Sourcing is an independent sourcing partner for US buyers who need a fuse holder paired with the fuse it must accept. We collect ratings, quantity and destination, then request factory wholesale quotes. We do not manufacture, hold inventory, or resell under a factory appointment.

What a fuse holder request has to settle

A fuse holder is not interchangeable with a neighbouring fuse, fuse block or fuse panel just because the ampere number matches. Class, body size and the holder ratings cap the assembly. Each check below is a buyer decision until a named supplier confirms the offered model.

Rating

State rated voltage with AC or DC and rated current in A. A holder published at 600 V AC / 30 A under UL/CSA on one supplier series is not a family-wide rating.

Interrupting

Ask for interrupting rating in kA, not as another ampere figure. Short-circuit current rating on a holder datasheet is a different event from the fuse ampere rating.

Class and body

Name Class CC, Class J, midget 10x38 or the measured body. Rejection features exist so a substitute cartridge does not seat. Guessing from appearance is not a specification.

Files

List datasheet, listing record and packing basis for the exact model. Series certificates are not evidence for the fuse you intend to buy.

Fuse holder questions before a factory can answer

Which purchasing requirements separate a fuse holder from neighbouring industrial fuse options?

The holder is the carrier: accepted body, poles, mounting, terminals and its own voltage and current limits. The fuse is the element: ampere rating, interrupting rating in kA, class and speed characteristic. A Class CC cartridge fuse, a Class J time delay fuse, a semiconductor fast acting fuse, an inline fuse holder and a DIN rail fuse block are five different line items, even when someone writes the same ampere number. Industrial Fuse Sourcing stays inside Industrial Fuses and Fuse Holders; we do not treat a circuit breaker as a drop-in replacement.

What does an independent sourcing request for a fuse holder have to contain?

One line per position: product type, intended application, rated voltage with AC or DC, rated current in A, interrupting rating in kA, class or body size, poles, mounting, terminal type, conductor range in AWG, quantity with units, destination state or ZIP, and requested delivery date. Optional budget may name currency and whether the figure is per unit or for the whole order. High-end, mid-range, budget or undecided is a buying preference, not a verified factory rating. No existing quotation is required to start.

Which part of the fuse holder specification stays the buyer’s decision?

Speed characteristic, class, whether the circuit is AC or DC, and whether you need indication remain open until you approve them. We restate gaps; we do not fill them with a catalogue default. Selective coordination and arc-flash studies belong to the buyer’s engineer, not to this website. Fuse versus circuit breaker is a protection-philosophy choice: fuses can limit fault current quickly; breakers can be reset and monitored. This site does not pick that architecture for you.

Do you hold stock or publish prices?

No. Availability, MOQ, packing and lead time come from the factories that answer the same written brief. We compare those replies on one basis. We do not publish a savings percentage because this site has no same-scope price comparison on file.

Who sends a fuse holder brief

Panel builders

Need holders that accept a stated class, fit 35 mm DIN rail, and match the conductor range already pulled to the enclosure. The drawing, not a photograph, is the source of truth.

Distributors

Need repeatable line items: same class, same poles, same indication option. Call-for-price distributor pages are not this site’s stock list.

OEM protection teams

Need the fuse and holder quoted as a pair so a 30 A element is not seated in a carrier rated below that current. Replacement must fit the existing cut-out.
