The 63 A rating on the C characteristic means the magnetic trip threshold is 5 to 10 times rated current (315–630 A), so it handles motor inrush and transformer energisation without nuisance tripping, while still clearing a hard short. The 2-pole configuration switches and protects both phase and neutral — typical for single-phase final circuits in commercial or residential distribution boards. Type A residual current detection (300 mA) catches pulsating DC fault currents from electronics like VFDs, LED drivers, and switched-mode power supplies, which a standard AC-only RCD would miss. ## Where it sits in the panel The 4-module width means it needs four 18 mm slots — plan the busbar and neutral bar layout accordingly. The RCBO replaces the separate MCB + RCD combination, saving one wiring step and one module of space versus discrete components.","metaTitle":"Siemens 5SU1624-7RC63 RCBO, 63 A 2-pole C char Type A 300mA","metaDescription":"Siemens 5SU1624-7RC63 RCBO, 63 A, 2-pole, C characteristic, Type A 300mA residual current.
