Rated residual current IΔn = 300 mA: this is a higher threshold than the 30 mA used for personal shock protection. It is selected for fire-prevention or equipment-protection duty where nuisance tripping from cable capacitance or surge suppressors must be avoided — common on long cable runs or in industrial sub-distributions where the upstream RCD is 300 mA and coordination is required. Breaking capacity 4.5 kA: this is the standard short-circuit rating for domestic and light-commercial final circuits in many European installations. For higher prospective fault levels (e.g. close to a transformer), an upstream back-up fuse or MCB with higher kA rating must coordinate. B-curve 13 A: the magnetic trip operates between 3 and 5 times rated current (39–65 A), suited for resistive and general-purpose loads — lighting, socket outlets, small appliances. Not ideal for motor starting (where C- or D-curve is preferred) but fine for most final circuits in a distribution board. Snap-on DIN-rail mounting, 70 mm width (four TE). The 1+N-Pol format switches the line conductor and disconnects the neutral, which is standard for single-phase final circuits in TN or TT systems. The Type A marking means it detects residual pulsating DC — required for circuits with single-phase rectifiers, switching power supplies, or electronic loads that can blind a Type AC device.","metaTitle":"Siemens 5SU1653-6KV13 FI/LS-Protector Type A, 13A B, 300mA,","metaDescription":"Siemens 5SU1653-6KV13 FI/LS-Protector Type A (PSE/SSF), 1+N-Pol, B 13A, 300mA, 4.5kA, 70mm.
