ABSTRACT:
A circuit breaker enclosure consists of a cover and a case designed for robotic assembly of the circuit breaker components. A current transformer assembly and a printed wire board containing the electronic trip unit circuit are precisely positioned within the case and cover by means of a transitory circuit breaker case support platform. The transitory support platform includes four upstanding posts that pass through openings formed in the circuit breaker case and are received within corresponding openings through the circuit breaker cover. Leads extending from the current transformer assembly within the case become automatically positioned within corresponding openings through the printed wire board by means of tapered lead-in openings formed within the circuit breaker cover.
