It delivers type AC residual-current detection at 300 mA and a C-curve overcurrent trip at 16 A, with a 4.5 kA breaking capacity. This is a 1+N-pole configuration: phase and neutral are switched, protecting single-phase circuits up to 230 V AC. Snap-mounts onto standard DIN rail in the distribution board. The 70 mm width (4 module spaces) fits alongside standard MCBs and RCCBs. The 300 mA residual threshold is less sensitive than the common 30 mA type, reducing nuisance tripping on circuits with natural leakage (long cable runs, multiple loads) while still providing fault protection.","metaTitle":"Siemens 5SU1653-1KV16 FI/LS Protector, 16A C, 300mA, 4.5kA","metaDescription":"Siemens 5SU1653-1KV16 FI/LS protector, type AC, 16A C-curve, 300mA residual, 4.5kA breaking capacity.

Type A additionally detects pulsating DC residual currents. The 5SU1653-1KV16 is type AC, so it is not suitable for circuits with rectified loads (e.g., washing machines, LED drivers, VFDs)."},{"question":"Where can I buy 5SU1653-1KV16?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
