Electronic circuit breaker, electronic circuit breaker subassembly, circuit breaker secondary electrical contact assembly, and powering methods

A circuit breaker secondary electrical contact assembly, comprising:

• a main contact terminal connectable to a main power terminal;
• a secondary electrical contact set having a stationary secondary electrical contact and a moveable secondary electrical contact;
• a lockout conductor provided in spring-engaged contact with the main contact terminal on a first end and including one of the stationary or moving secondary electrical contacts on a second end;
• and
• a spring having the moveable secondary electrical contact provided on a moveable portion.

A method of powering a printed circuit board of a circuit electronic circuit breaker, comprising:

• providing a main contact terminal coupled to a main power terminal;
• providing a secondary electrical contact set having a stationary secondary electrical contact and a moveable secondary electrical contact, the moveable secondary electrical contact being coupled to a spring;
• electrically connecting a lockout conductor in spring-engaged contact with the main contact terminal on a first end and to one of the stationary secondary electrical contact or moving secondary electrical contact on a second end;
• and
• receiving power at a printed circuit board by contacting the spring with a handle extension to close the secondary electrical contact set.

An electronic circuit breaker, comprising:

• a moveable contact arm;
• and
• a lockout mechanism operable to block motion of the moveable contact arm, the lockout mechanism having
• a lockout latch operatively pivotal about a pivot axis, a moveable stop adapted to contact the moveable contact arm, the moveable stop including an end latching surface having a non-90 degree angle configured to have a normal vector, and an engagement portion offset from the pivot axis, and
• an actuator operative to provide an unlock force at the engagement portion causing pivoting of the lockout latch about the pivot axis and release of the moveable contact arm wherein the end latching surface having a non-90 degree angle biases the lockout latch to a blocking condition.
