The 10 A rating at 30 °C derates to 9.6 A at 40 °C, 9.1 A at 50 °C, and 8.2 A at 70 °C; if the distribution board runs warm, size the upstream protective device accordingly. Supply can enter from either the top or bottom, which simplifies busbar alignment and panel wiring. The 4-pole design with all poles protected (4P) means it switches and protects all four conductors — three phases plus neutral — in a single module, saving DIN-rail space compared to separate MCB and RCCB units. The 72 mm wide module occupies 4 standard modular-width units on a DIN rail. Depth is 72 mm, installation depth 70 mm — verify enclosure depth clearance before committing, especially in shallow consumer units. The 85 mm height fits standard distribution board cutouts.","metaTitle":"Siemens SENTRON 5SU1646-7FP10 RCBO, 4P, C-curve, 10 A, 6 kA","metaDescription":"Siemens SENTRON 5SU1646-7FP10 RCBO, 4-pole, C-curve, 10 A rated at 30 °C, 6 kA per EN 60898 & IEC 60947-2.
