What is a low-voltage fuse?
A fuse uses a calibrated element that melts when current exceeds its time-current characteristics, interrupting the circuit. After operation, the fuse link must be replaced with the correct compatible rating and type.
The complete assembly may include a fuse link, holder, base or switch disconnector. Rated current, voltage, utilization category, breaking capacity, size and AC or DC suitability must be coordinated.

How to choose a fuse system
Select the fuse link and its holder or disconnector as one coordinated assembly.
Corrente e tensão nominais
Match the circuit conditions and avoid using an AC-only rating for an unapproved DC application.
Capacidade de interrupção
Confirm the fuse can interrupt the prospective fault current at the specified voltage.
Fuse size and product form
Match the fuse-link dimensions, holder, mounting method and conductor arrangement.
Categoria de utilização
Choose the operating class and time-current behaviour required by the protected circuit.
One coordinated fuse assembly
A fuse link, holder and switch disconnector perform different roles. Verify compatibility before ordering.

Fuse Selection Questions
Respostas rápidas para comparação preliminar de famílias de produtos antes da verificação detalhada do circuito.
What is the difference between a fuse link and a fuse holder?
The fuse link contains the calibrated element that interrupts overcurrent. The holder supports connection, installation and replacement of a compatible fuse link.
Can a fuse be reused after it operates?
No. An operated fuse link must be replaced with the correct compatible type and rating after the cause of the fault is resolved.
Can an AC fuse be used in a DC circuit?
Not unless the product is explicitly rated for the DC voltage and application. DC interruption can require different construction and ratings.
Which details are needed to select a fuse?
Confirm rated current, voltage, AC or DC system, utilization category, breaking capacity, physical size and the compatible holder or disconnector.
What does a fuse switch disconnector add?
It combines fuse-link based protection with a mechanism intended for controlled isolation. Exact switching and protection ratings must be checked on the product documentation.
Need the Right Fuse System?
