2 Terms and definitions

2.1 fuses and their components

2.1.1

Fuse fuse

When the current exceeds the specified value for a sufficient time, the current is interrupted by melting one or several specially designed proportional components to break it

A device that accesses the loop. The fuse includes all the components that make up the complete device.

2.1.2

Terminal

A conductive component of a fuse connected to an external circuit.

Note. Terminals can be distinguished by circuit type (such as main terminal, grounding terminal, etc.) or by structure (such as screw terminals, plug terminals, etc.).

2.1.3

Fuse base fuse-base; fuse-mount

A fixed part of a fuse with contacts and terminals.

2.1.4

Fuse base contact fuse-basecontact

Contact parts on the fuse base that engage the fuse or fuse contacts.

2.1.5

Fuser-carrier

A movable part of a fuse for loading a fuse.

2.1.6

Fuser contact fuse-carriercontact

Contact member of the load carrying member that engages the fuse base contact.

2.1.7

Fuse holder fuse-holder

A combination of a fuse base and a load carrying member.

2.1.8

Fuse-use

A fuse component including a melt to be replaced after the fuse is actuated.

2.1.9

Fuse contact fuse-linkcontact

Contact member of the fuse that engages the fuse base contact or the carrier member contact.
