Abstract
There is described a switching device whose disconnection cause can be identified, and a method for displaying the disconnection cause of a switching device. The switching device has a switch latch for mechanical activation of the switching device, a first tripper for overload protection, a second tripper for short-circuit protection, and a handle for activating the switch latch. The switching device is embodied in such a way that the handle is moved to a first position or a second position if the first tripper or second tripper is tripped, with the first position and the second position being different.
Claims18
A switching device, comprising:
- a switch latch for mechanical activation of the switching device;
- a first tripper for overload protection;
- a second tripper for short-circuit protection;
- a handle for activation of the switch latch, wherein the handle is moved to a first position if the first tripper tripped, and wherein the handle is moved to a second position if the second tripper is tripped, wherein the first position and the second position are different.
A method to display a disconnection cause of a switching device, comprising:
- providing the switching device having a first tripper for overload protection, a second tripper for short-circuit protection, a switch latch for mechanical activation of the switching device, and a handle for activation of the switch latch;
- and
- moving the handle to a first position if the first tripper is tripped;
- moving the handle to a second position if the second tripper is tripped, wherein the first position and the second position are different.
A power switch, comprising:
- a switch latch for mechanical activation of the power switch;
- a first tripper for overload protection;
- a second tripper for short-circuit protection;
- a handle for activation of the switch latch, wherein the handle is moved to a first position if the first tripper tripped, and wherein the handle is moved to a second position if the second tripper is tripped, wherein the first position and the second position are different, wherein the handle is in a third position, when the switching device is switched on, wherein the handle is in a fourth position, when the switching device is switched off, and wherein the four positions are different positions.
