DIN-rail fit and panel integration
Width is 36 mm (2 modular units), depth 76 mm, installation depth 70 mm. Snaps onto any standard DIN rail via the quick-assembly system; mounting position is unrestricted. The IP20 rating with connected conductors means it is protected against finger contact but not washdown — keep it inside a sealed enclosure on the train or in the panel. Combined terminals top and bottom accept both busbar and cable; the breaker is sealable for anti-tamper requirements in metered or safety-critical circuits. Halogen-free and silicon-free construction matters if the panel is in a tunnel or confined space where smoke toxicity is a specification gate.
