A debris barrier is for an electrical switching apparatus. The electrical switching apparatus includes separable contacts and an arc chute. The separable contacts generate debris when tripping open in response to an electrical fault. The arc chute has a plurality of splitter plates each having an edge portion and a distal portion located opposite and distal the edge portion. The debris barrier includes a first leg, a second leg, and a middle portion connecting the first leg and the second leg. The middle portion is coupled to one of the separable contacts. At least one of the first leg and the second leg has a first barrier portion and a second barrier portion extending therefrom. The first barrier portion is located proximate the distal portion. The second barrier portion extends from the first barrier portion toward the edge portion in order to redirect the debris toward the edge portion.

The present invention relates to a circuit breaker (20, 40) comprising a handle (33) connected to a switching and trip mechanism (25) in the base unit (20a), and capable of opening and closing a system (24) of electrical contacts in normal operation, ensuring the interchangeability between a pluggable electronic trip module (20b) and/or a pluggable thermomagnetic trip module (20b), using the same structural base unit (20a). The device comprises a main electric circuit 1 and a secondary circuit 2 or 2b, wherein the main circuit 1, using a current transformer (29) in the base unit (20a) which converts a current flowing in the main circuit 1 of the power line (23) to power the secondary circuit 2 or 2b, issues a trip command to protect the main circuit 1, opening the contact system (24) when predefined current limits are exceeded.

A liquid-cooled heat dissipation apparatus includes a base (10), a telesignaling linkage member (20), a sliding plate (30) and a switch module (40). The telesignaling linkage member (20) is moveably installed on the base (10). The sliding plate (30) is installed corresponding to the telesignaling linkage member (20) and generates a movement along with the telesignaling linkage member (20). The switch module (40) includes a microswitch (41) arranged corresponding to the sliding plate (30) such that the microswitch (41) is operably opened or closed based on the movement of the sliding plate (30). Accordingly, through the opening and closing of the microswitch, the telesignaling monitoring on the functional module state can be achieved.
