Abstract

An improved multi-pole circuit interrupter includes an improved trip deck assembly adjacent one pole and further includes an accessory deck adjacent another pole. The accessory deck includes conventional accessory devices such as an auxiliary switch, etc., and the trip deck assembly includes switches and one or more other devices that can interact with a crossbar and a trip bar of the circuit interrupter. Such switches can be easily installed by a technician in the field after manufacture of the circuit interrupter. One switch is held in place by a support, and the other switch is held in place by a retainer, with the support and the retainer holding the switches in a fixed position on the trip deck assembly in order to interact with the crossbar and the trip bar.

First claim

What is claimed is:

1. A combination comprising: a support; and a switch; the support being structured to mount the switch to a platform; the switch having a housing and further having a plunger that is movably situated on the housing to change the switch between a first state and a second state; the support comprising: a base engaged with the housing, the base having an opening formed therein receives therethrough at least a portion of at least one of the housing and the plunger; a number of walls situated on the base; a mounting apparatus that is structured to be usable to affix the number of walls to the platform; and a receptacle that is situated adjacent the base and the number of walls and that receives the housing therein; the trip deck assembly being structured to be usable with a circuit interrupter having a plurality of poles, a crossbar, and a trip bar, the circuit interrupter being movable among a plurality of conditions that include an ON condition, an OFF condition, and a TRIPPED condition, the trip deck assembly further comprising:
a platform apparatus upon which the mounting apparatus is situated, the platform apparatus being, structured to be affixed to the circuit interrupter;
the plunger being structured to be in a first position engaged with the crossbar to cause the switch to be in its first state in the ON condition, the plunger being structured to be in a second position different from first position to cause the switch to be in its second state in the OFF condition and the TRIPPED condition; and
another switch disposed on the platform apparatus and having another housing and further having another plunger that is movably situated on the another housing to change the another switch between a first state and a second state, the another plunger being structured to be in a first position engaged with the trip bar to cause the another switch to be in its first state in the ON condition and the OFF condition, the another plunger being structured to be in a second position different from first position to cause the another switch to be in its second state in the TRIPPED condition.

2. The trip deck assembly of claim 1 wherein the platform apparatus comprises a processing system with which the switch and the another switch are electrically connected, the processing system being structured to generate an output depending upon whether the switch is in its first state or its second state and further depending upon whether the another switch is in its first state or its second state.

3. The trip deck assembly of claim 1 wherein the platform apparatus further comprises a trip actuator structured to operatively engaged the trip bar in a number of predetermined conditions.

4. A circuit interrupter comprising the rip deck assembly of claim 1 , the circuit interrupter further comprising:
a frame;
a plurality of poles situated on the frame and each comprising a set of separable contacts;
a crossbar situated on, the frame and operatively connected with each set of separable contacts; and
a trip bar situated on the frame and operatively connected with the crossbar;
the circuit interrupter being movable among a plurality of conditions that include an ON condition, an OFF condition, and a TRIPPED condition;
the plunger being in the first position engaged with the crossbar to cause the switch to be in its first state in the ON condition, the plunger being in the second position to cause the switch to be in its second state in the OFF condition and the TRIPPED condition; and
the another plunger being in the first position engaged with the trip bar to cause the another switch to be in its first state in the ON condition and the OFF condition, the another plunger being in the second position to cause the another switch to be in its second state in the TRIPPED condition.

5. The circuit interrupter of claim 4 , wherein the frame comprises an accessory deck situated adjacent a pole of the plurality of poles, the accessory deck being structured to have a number of accessory devices mounted thereon, and wherein the trip deck assembly is situated on the frame adjacent another pole of the plurality of poles.
