three phase circuit breakers for use in oil filled distribution transformers. These breakers come with the signal light and emergency overload features. Breakers may be ordered separately or as a breaker on a bracket.<\/span><\/p><p><span style=\"font-weight: normal;\"><br><\/span><\/p>\n<p><span style=\"font-weight: normal;\">The circuit breaker is typically mounted inside the transformer directly above the core\/coil assembly.
