Abstract
A device for recognizing an arcing fault in incident light that includes a sensor for detecting absorption lines of the incident light, and an evaluation unit which generates an evaluation signal when characteristic absorption lines are detected.
Claims17
A trigger element comprising:
- an actuating member of a pressure trigger for an electric switch, the pressure trigger being provided with at least one flow channel for each of at least one electric pole of the electric switch, the at least one electric pole of the electric switch including at least two switch contacts for making or breaking a current path,
- wherein the at least two switch contacts of the at least one electric pole of the electric switch being disconnectable via the actuating member, the actuating member being configured to respond to an increase in pressure generated by an electric arc drawn during electrodynamic recoil of the at least two switch contacts in a separation zone of the at least two switch contacts, wherein, through the increase in pressure generated by the electric arc, the pressure trigger is set into motion,
- wherein the separation zone is connectable to the actuating member via the at least one flow channel, and
- the actuating member being guidable by a housing of the trigger element between a neutral position and a trigger position, wherein, after the trigger position has been reached, the pressure trigger is configured such that a relief of pressure vents the pressure trigger, wherein the actuating member is movable in a guide of the housing and wherein a recess in the guide of the housing is configured to bring about the relief of pressure of the pressure trigger in the trigger position.

A pressure trigger comprising:
- a trigger element, the trigger element including
- an actuating member of the pressure trigger for an electric switch, the pressure trigger being provided with at least one flow channel for each of at least one electric pole of the electric switch, the at least one electric pole of the electric switch including at least two switch contacts for making or breaking a current path,
- wherein the at least two switch contacts of the at least one electric pole of the electric switch being disconnectable via the actuating member, the actuating member being configured to respond to an increase in pressure generated by an electric arc drawn during electrodynamic recoil of the at least two switch contacts in a separation zone of the at least two switch contacts, wherein, through the increase in pressure generated by the electric arc, the pressure trigger is set into motion,
- wherein the separation zone is connectable to the actuating member via the at least one flow channel, and
- the actuating member being guidable by a housing of the trigger element between a neutral position and a trigger position, wherein, after the trigger position has been reached, the pressure trigger is configured such that a relief of pressure vents the pressure trigger, wherein the actuating member is movable in a guide of the housing and wherein a recess in the guide of the housing is configured to bring about the relief of pressure of the pressure trigger in the trigger position.
