It packs a Type A RCD (sensitive to pulsating DC fault currents up to 6 mA smooth DC, per IEC 60755) and a B-curve MCB into a single 1+N-Pol module. The 300 mA residual trip threshold means it's sized for protection against fire risk from earth faults rather than personnel shock protection (that's the 30 mA version's job). ## Deployment context and panel fit The 70 mm depth (D=70 mm) is standard for Siemens 5SU series devices, so it sits flush with adjacent breakers and RCDs. The 1+N-Pol construction switches and protects the phase conductor only; the neutral bar passes through the residual-current transformer but is not switched — verify your neutral bar arrangement in the panel before committing the BOM line.","metaTitle":"Siemens 5SU1653-6KV10 FI/LS Protector, Type A, B 10A, 300mA,","metaDescription":"Siemens 5SU1653-6KV10 FI/LS protector Type A (PSE/SSF), 1+N-Pol, B 10A, 300mA, 4.5kA.
