An arc baffle includes a first baffle member having a number of first venting holes disposed therein, each being structured to receive ionized gases produced by an arcing event; a second baffle member having a number of second venting holes disposed therein; a section of porous material disposed between the first baffle member and the second baffle member; and a cover disposed adjacent the second baffle member on the opposite side of the section of porous material. The first venting holes are laterally spaced from the second venting holes by a predetermined distance such that ionized gases produced by the arcing event passing through one of the first venting holes must travel at minimum the predetermined distance generally along the section of porous material before passing through one of the second venting holes.

A gas segregator barrier is for quenching, segregating and controllably directing ionized gases discharged from a pair of spaced-apart circuit breakers double-branch mounted within a panelboard assembly. The spaced-apart circuit breakers include corresponding pairs of opposing poles, and a housing with exhaust vent openings for discharging ionized gases developed from an electrical fault. The gas segregator barrier includes at least substantially parallel segregator fins divided into first and second portions by a transverse dividing member. Baffles in the transverse dividing member quench the ionized gases and provide fluid communication between exhaust channels formed between the segregator fins of the first portion, and gas ducts disposed between the segregator fins of the second portion. The gas ducts include one or more lateral members structured to controllably direct the discharged ionized gases.

The magnetic trip device of a circuit breaker has a magnetic pole in which a magnetic field is generated by load current, and an armature assembly that includes: a bracket supported for pivotal movement relative to the magnetic pole; a spring biasing the bracket to a position spaced from the magnetic pole; an armature hinged on the bracket; and an adjusting screw for adjusting a gap between the armature and the magnetic pole for calibrating the trip device without affecting the spring bias, which can be separately and independently adjusted to select the load current at which the magnetic trip is initiated.
