Abstract
A circuit breaker includes a housing and a circuit interrupter. An indicator is movable between first and second positions corresponding to the respective closed and open breaker positions. A first indicia is indicative that the circuit interrupter is in the closed breaker position and a second indicia is indicative that the circuit interrupter is in the open breaker position. An opening is formed on the housing and aligned with the indicator to expose for view the respective first or second indicia when the circuit interrupter is in the respective closed or open breaker position.
Claims14
A circuit breaker, comprising:
- a housing;
- at least one circuit interrupter mounted within the housing;
- an indicator operatively connected to said at least one circuit interrupter and movable between first and second positions corresponding to closed and open breaker positions of the at least one circuit breaker, said indicator having a first indicia indicative that the at least one circuit interrupter is in the closed breaker position and a second indicia indicative that the at least one circuit interrupter is in the open breaker position;
- an opening formed on the housing and aligned with the indicator to expose for view the first indicia or the second indicia when the at least one circuit interrupter is in the closed breaker position or the open breaker position, respectively;
- and
- a light guide mounted adjacent the opening within the housing and configured to guide light from outside the housing onto the indicator, said light guide comprises a light tunnel having a light entrance at the opening and extending within said housing, a light exit adjacent the indicator, and an interior reflective surface between the light entrance and the light exit.
An outdoor circuit breaker, comprising:
- a housing;
- at least one circuit interrupter mounted within the housing and having first and second terminals;
- first and second terminal bushings mounted on the housing, each of the terminal bushings having a lower terminal end extending into the housing and electrically connected to respective first and second terminals of the at least one circuit interrupter;
- an indicator operatively connected to said at least one circuit interrupter and movable between first and second positions corresponding to the closed and open breaker positions of the at least one circuit interrupter, said indicator having a first indicia indicative that the at least one circuit interrupter is in the closed breaker position and a second indicia indicative that the at least one circuit interrupter is in the open breaker position;
- an opening formed on the housing and aligned with the indicator to expose for view the first indicia or the second indicia when the at least one circuit interrupter is in the closed breaker position or the open breaker position, respectively;
- and
- a light guide mounted adjacent the opening within the housing and configured to guide light from outside the housing onto the indicator,
- said light guide comprises a light tunnel having a light entrance at the opening and extending within said housing to a light exit adjacent the indicator, and an interior reflective surface between the light entrance and the light exit.
