FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, particularly to differential current transformers incorporated with protective circuit breakers. Built-up housing (20) for magnetic device (1) to accommodate differential transformer circular magnetic core (2) made from insulating material. Housing (20) has at least two conducting terminals (5) to connect ends (6) of at least one conducting loop (6) of, for example differential current transformer secondary and/or tertiary (4). Conducting terminals (5) represent leadouts (8) of at least one plug-in electronic component (9).
EFFECT: facilitated automatic production of protection circuit breakers.
