Abstract: An arc bypass assembly for use in a circuit breaker includes: an arc chute including a base, two arc sides extending from the base, and a plurality of arc plates arranged within the two arc sides, the arc chute structured to dissipate an arc upon opening of primary contacts of the circuit breaker during a high current event; an arc horn extending outwardly from a first edge of the base of the arc chute toward a primary stationary contact coupled to a line-in conductor, the arc horn structured to attract the arc; and an arc bypass wire coupled to the base of the arc chute at one end and to a secondary stationary arm of the circuit breaker at another end, where the arc bypass assembly is structured to redirect a portion of current generated during the high current event to the load.

Abstract: A UV disinfection system including at least one UV lamp assembly with a sleeve surrounding a UV lamp and defining an inner volume. The UV disinfection system further includes at least one pressure sensor. At least one non-return valve connects the inner volume of the at least one sleeve to the pressure sensor. The UV disinfection system is configured to detect a sleeve breakage by the resulting change in pressure at the at least one pressure sensor. A break detection device for a UV disinfection system with a pressure detector includes at least one tubing which communicates directly or indirectly with an inner volume of a sleeve surrounding at least one of a UV lamp unit.
