Abstract
An apparatus includes a housing (e.g., a housing having a form factor of a molded case circuit breaker) and at least two phase terminals supported by the housing and configured to be connected to respective ones of at least two phase buses in an electrical panelboard. The apparatus further includes at least one fault generation device supported by the housing and including an arc containment chamber and first and second spaced-apart electrodes in the arc containment chamber and electrically coupled to respective ones of the at least two phase terminals.
Claims8
An apparatus comprising:
- a cylindrical body;
- first and second end caps covering first and second ends of the cylindrical body to define an arc containment chamber;
- first and second cylindrical electrodes extending through respective ones of the first and second end caps into the arc containment chamber, the first and second electrodes having longitudinal axes aligned with a longitudinal axis of the body and having a gap therebetween in the arc containment chamber;
- and
- a trigger conductor extending across an end of the first electrode in the gap and facing an end the second electrode.
An apparatus comprising:
- a housing having a molded circuit breaker housing form factor;
- first, second and third bus bars in the housing and having respective terminals for connection to first, second and third phase conductors;
- a first fault generation device in the housing and connected between the first and second bus bars;
- and
- a second fault generation device in the housing and connected between the second and third bus bars.
