FIELD: electricity.
SUBSTANCE: vacuum chamber is encapsulated together with moulding core which is attached to it on its lower cover. Before encapsulation, on outer circumferential line of vacuum interruption chamber cover or close to it, compensation ring is accommodated as separate die cast-moulded seal between lower cover of interruption vacuum chamber and moulding core, and then also encapsulated so that it stays as residual seal in sheath. Then, moulding core is removed.
EFFECT: excluding necessity to make expensive reinforcement of interruption vacuum chamber against force impacts during die-casting on switching contact side in the area of moulding core.
