LV multi-pole circuit breaker - has pair of contact blades fixed to cross bars linking slotted side plates

摘要

The multiple low-voltage disconnector has a chassis comprising two plates. Each plate has slots symmetric about a median plane parallel to the alignment direction of the sets of input and output contacts of each of the disconnector's poles. A rear support engages in the slots to mount the disconnector to the chassis. Two insulating cross members are fixed to the plates to maintain the chassis rigid and to support the two sets of contacts.
