B-curve characteristic (3-5 In magnetic trip) suits resistive and light inductive loads like lighting circuits, small heaters, or control transformers. At 4 modules wide (roughly 72 mm), it occupies the same footprint as a 4-pole MCB plus a separate RCD — but in one package, saving one DIN position and reducing wiring. The 96 x 40 x 82 mm envelope fits alongside other SENTRON 5SU series devices for clean busbar or comb-bridge feeding. Rated 400 V line-to-line, so it goes on a 3-phase 4-wire system (-L2-L3-N) with the neutral switched internally.","metaTitle":"Siemens 5SU1646-6FP06 RCBO, 6A B-Char, 300mA, 6kA, 4P","metaDescription":"Siemens 5SU1646-6FP06 RCBO, 6kA, 4P Type A, 300mA, B-Char, 6A, 400V.
