Abstract
An electrical switching apparatus includes a plurality of poles, each of the poles including a terminal. The terminal of a first one of the poles is proximate the terminal of a second one of the poles. A jumper is electrically connected between the terminal of the first one of the poles and the terminal of the second one of the poles. The jumper includes a plurality of heat transfer members, each of the heat transfer members being separated from others of the heat transfer members.
Claims15
An electrical switching apparatus comprising:
- a plurality of poles, each of said poles comprising a terminal, the terminal of a first one of said poles being proximate the terminal of a second one of said poles;
- a plurality of bolts:
- and
- a jumper electrically connected between the terminal of the first one of said poles and the terminal of the second one of said poles, said jumper comprising a plurality of heat transfer members, each of said heat transfer members including a first end and a second end distal from the first ends of said heat transfer members being connected to the terminal of a corresponding one of said poles by a corresponding one of said bolts, the second end of each of said heat transfer members being spaced apart from the second end of others of said heat transfer members,
- wherein said plurality of heat transfr members is at least three heat transfer members;
- wherein each terminal has a first side and a second side disposed opposite the first side;
- wherein one of said heat transfer members is mounted on the first side of the terminal;
- and wherein all of the others of said heat transfer members are mounted on the second side of the terminal.
An electrical switching apparatus comprising:
- a plurality of poles;
- a plurality of pairs of separable contacts:

- and wherein all of the others of said heat transfer members are mounted on the second side of the terminal.
A jumper for an electrical switching apparatus comprising a plurality of poles and a plurality of bolts, each of said poles comprising a plurality of terminals, one of the terminals of a first one of said poles being proximate one of the terminals, one of the terminals of a first one of said poles being proximate one of the terminals of a second one of said poles, said jumper comprising:
- a jumper member structured to be electrically connected between said one of the terminals of the first one of said poles and said one of the terminals of the second one of said poles, said jumper member comprising:
- a plurality of heat transfer members,
- wherein each of said heat transfer members includes a first end and a second end distal from the first end,
- wherein the first ends of said heat transfer members are structured to be connected to the terminal of a corresponding one of said poles by a corresponding one of said bolts,
- wherein the second end of said heat transfer members is separated from the second end of others of said heat transfer members, and
- wherein said plurality of heat transfer members is at least three heat transfer members;
- wherein each terminal has a first side and a second side disposed opposite the first side;
- wherein one of said heat transfer members is mounted on the first side of the terminal;
- and wherein all of the others of said heat transfer members are mounted on the second side of the terminal.
