Proper name for these circuit breakers

[zam]

Good morning. Please take a look at the attachment. What would be the proper name for these type of circuit breakers? Thank you.

Fused pullouts is a common name.

That's what I call them.

Fuse block.
Fusible Pullout (Switch)

A fuse pullout, when either a fuse blows, or the block is pulled out, disconnects the load, or "breaks the circuit". But, in no way is the fuse pullout a circuit breaker as defined in Article 100 Definitions of the NEC. The difference hinges in the operation of a fuse, which when blown must be replaced with a new fuse every incident.

Fuse blocks, or more precisely pull out fuses as others have mentioned.

I've often wondered if fused pull-outs are rated for opening under load, your response made me go look. It appears they are.

I've done that research before, as well. Every time I face using a pullout as a disconnect for a load that might be energized, I get myself centered and lined up to quickly yank the block out.

There are lots of ways I can imagine that could result in some plasma welding, or cutting, or . . . . :thumbsdown:

Pulling them isn't normally as much concern for me, I am usually more concerned about what happens if I am closing them into a fault, especially at some old farm place where they have a meter main with a 200 amp pullout on the main distribution pole and the source transformer is only 20' up the same pole.
