Neutral link, open

The open neutral link shows the link withdrawn so that the neutral is disconnected. Drawings use it where a circuit is normally run with the neutral open, for example to isolate a spare or to segregate a neutral during a changeover, and on test procedures that show the link removed.

N

IEC

Neutral link, closed

A neutral link is a bolted or plug-in link in the neutral conductor, often mounted in a fuse carrier style holder alongside phase fuses. It allows the neutral of a circuit to be disconnected for insulation testing or fault finding without disturbing other circuits on the neutral bar. The closed form shows its normal service state.

A distinction that matters

A closed neutral link is a removable connection; a neutral fuse would be a protective device and is generally not permitted.
