The SIGRES designation means it is built for harsh ambient conditions — condensation, corrosive atmospheres, or high humidity — where standard RCCBs may nuisance-trip or degrade. Mounting position is unrestricted, and supply can be fed from top or bottom; for SIGRES function, feed from top even in the switched-off state. ## SCCR and selectivity headroom The 5SV3646-6KK12 carries a short-circuit current rating of 10 kA, with a rated conditional short-circuit current of 0.8 kA. The permissible series fuse can be up to 100 A, giving selectivity margin against upstream MCBs or fuses in a 400 V panel.","metaTitle":"Siemens 5SV3646-6KK12 RCCB, 4-pole Type A, 63A 300mA, SIGRES","metaDescription":"Siemens SENTRON 5SV3646-6KK12 RCCB, 4-pole, Type A, 63 A, 300 mA, 400 V AC.

The 5SV3646-6KK12 is Type A, making it suitable for circuits with electronic loads that generate pulsating DC fault currents."},{"question":"Can the 5SV3646-6KK12 be used in outdoor installations?","answer":"The IP20 rating applies only when installed in a distribution board with conductors connected.
