Integration and mounting
Snaps onto a DIN rail via the quick-assembly system, occupying one modular width (18 mm). Mounting position is any orientation, which simplifies layout in cramped railway cabinets. Installation depth is 70 mm; overall depth including terminals is 76 mm. IP20 with connected conductors — standard for enclosed panel mounting. Pollution degree 3 and overvoltage category III are rated for the industrial/railway environment. Combined terminals at top and bottom accept both busbar and cable, and the design allows add-on auxiliary switches or shunt trips via the product extension slot.
