It's a Type A RCD (sensitive to pulsating DC fault currents, as well as sinusoidal AC) paired with a B-curve MCB rated 25 A, in a 1+N-pole package. Type A RCD means it's safe for circuits feeding single-phase electronics (VFDs, switch-mode power supplies) that generate pulsating DC leakage. The 30 mA IΔn is the standard for personal shock protection per IEC 60364. At 70 mm deep (D=70 mm) it fits standard distribution boards with no depth conflict.","metaTitle":"Siemens 5SU1353-6KV25 FI/LS Protector Type A, 25A B-Curve, 3","metaDescription":"Siemens 5SU1353-6KV25 FI/LS-protector Type A (PSE/SSF), 1+N-pole B 25A, 30mA IΔn, 4.5kA breaking capacity.
