That places it in the standard category for fixed-installation switchgear in building and industrial panels. Snap-on mounting to DIN rail EN 60715; the 72 mm width occupies 4 modular width units. Depth is 72 mm, installation depth 70 mm — fits standard distribution boards with that clearance. All four poles are protected (4 poles with protection), and the design is instantaneous — no intentional time delay on the residual-current function. The energy limitation class is 1, which means it limits let-through energy in a fault condition to the lowest category per standards, reducing stress on downstream components.","metaTitle":"Siemens 5SU1346-7FP20 SENTRON RCBO, 4P, C-20A, 6kA","metaDescription":"Siemens 5SU1346-7FP20 SENTRON RCBO, 4-pole, C-curve 20A, 6kA breaking capacity per EN 60898.
