Device is dust-proof and moisture-proof.

The assembly consists of an upper and a lower unit, lever and the cover with 3 self-locking nuts.

Lower unit includes the plastic case, bus bar with static contacts, adjustment nodes and bimetallic cut-offs,

plus electromagnetic cut-offs for 20 A – 100 A switches. General dust- and moisture-proofing is provided by a seal assembly and a rubber filler.
