It integrates Type A earth-leakage detection at 300 mA with a C-curve overcurrent trip rated 13 A, breaking capacity 6 kA. The 70 mm depth fits standard Siemens distribution boards alongside other 1+N RCBOs. The 300 mA IΔn is a fire-protection threshold, not a personnel-protection threshold (30 mA is typical for shock protection); this unit is sized for circuits where nuisance tripping from leakage on longer cable runs or equipment with filters would be unacceptable. The C-curve characteristic (magnetic trip at 5–10× In) handles inrush from motorized loads, pumps, and compressors without nuisance tripping, while the 13 A thermal element protects the downstream wiring. For BOM-line commitment, the key fit criteria are the Type A + 300 mA + C-curve 13 A combination. If your panel design calls for a 1+N RCBO with those exact parameters, this order code is the direct Siemens match.","metaTitle":"Siemens 5SU1656-7KV13 FI/LS Protector, Type A, 300mA, 6kA, C","metaDescription":"Siemens 5SU1656-7KV13 FI/LS combination unit.
