Fully enclosed electronic trip unit for a molded case circuit breaker

摘要: A molded case circuit breaker having a trip unit (100) with one or more integrally formed dielectric protrusions (102) that are configured to slidably interconnect corresponding members (202) of the base (200) when is secured (200). The extend from walls (122) located between adjacent enclosure chambers (109) house current transformers (114) and remain in contact as being moved respect By remaining another while (200), (102), along (202), maintain strong barrier within exterior spaces (112) transformer (109), thereby preventing debris traveling accumulating on
