Abstract
A multi-pole circuit breaker such as a residential electronic circuit breaker is provided. It includes a means to prevent a breaker mechanism from latching, i.e., a breaker armature from latching with a cradle if certain criterion is met. In particular, the multi-pole circuit breaker comprises a breaker mechanism including a breaker armature, a cradle and an armature latch bar to prevent the breaker armature from latching with the cradle. The armature latch bar includes a recessed feature that interfaces with the breaker armature, an armature latching surface that needs to be removed before the breaker mechanism can be latched and an armature latching lever that prevents a rotation of the breaker armature.
Claims20
A multi-pole circuit breaker comprising:
- a breaker mechanism including a breaker armature;
- a cradle;
- and
- an armature latch bar to prevent the breaker armature from latching with the cradle, wherein the armature latch bar includes:
- a recessed feature that interfaces with the breaker armature,
- an armature latching surface that needs to be removed before the breaker mechanism can be latched, and
- an armature latching lever that prevents a rotation of the breaker armature.
A ground fault circuit interrupter (GFCI) and/or a combination arc-fault circuit interrupting (CAFCI) two or three pole residential circuit breaker comprising:
- a breaker mechanism including a breaker armature;
- a cradle;
- an armature latch bar to prevent the breaker armature from latching with the cradle, wherein the armature latch bar includes:
- a recessed feature that interfaces with the breaker armature,
- an armature latching surface that needs to be removed before the breaker mechanism can be latched, and
- an armature latching lever that prevents a rotation of the breaker armature;
- a breaker trip bar that includes a recessed area to interface with the armature latch bar;
- and
- a printed circuit board (PCB) assembly including an electronic circuitry to activate at least one of a solenoid assembly and an electromagnet.
