Definitions
- the invention relates to an electrical installation device, in particular a circuit breaker, according to the preamble of claim 1.
- an installation device is known from document DE-195 249 15.
- Installation switchgear of this type serves for an overcurrent or a short-circuit current off.
- the contact pieces are arcing plates assigned, in the case of a switch-off between the fixed and arcing generated in the movable contact piece runs to its quenching.
- the object of the invention is to define the ring-shaped electromagnetic field, that is to say the blowing field, to strengthen and focus.
- an insulating plate is arranged on each of them, which defines the arcing area limited on both sides; is located behind the insulating plates an iron plate, the iron plate that is on the side of the loop, is arranged within the loop or the loop the iron sheet on his At least partially surrounds the outer circumference.
- Fig. 1 shows the arcing area of a circuit breaker, in which is a fixed contact piece 11 attached to an arc guide rail 10 as well as a movable contact piece 12, which is located on an axis 13 pivotable contact lever 14 is attached.
- a further arc guide rail 15 is assigned to the arcing area, which is composed of a plurality of arc-extinguishing plates 16 on both sides 17 limit.
- Fig. 2 shows the arrangement along section line II-II of Fig. 1.
- the loop 18 is located outside the insulating plate 22.
- a first iron plate 23 is provided inside the loop 18, that is practically in one plane therewith.
- a second iron plate 24 is provided inside the loop 18, that is practically in one plane therewith.
