It integrates Type A earth-leakage detection at 30 mA with a B-curve overcurrent trip rated at 10 A, all in a 70 mm-wide housing. The Type A classification means this device detects AC pulsating DC earth faults and smooth DC residual currents up to 6 mA — required on circuits feeding single-phase rectified loads like washing machines, LED drivers, or IT equipment. ## Panel integration The 70 mm module width (4 module spaces on a standard 18 mm DIN rail) fits standard distribution boards and consumer units. The 1+N-pole configuration switches the line conductor only; the neutral is switched internally for isolation but is not overcurrent-protected. Wire terminations accept solid or stranded copper conductors typical of final subcircuits. No auxiliary contact or shunt-trip accessory is integrated — external add-on modules from the Siemens 5SM series can be fitted for remote signaling or undervoltage release.","metaTitle":"Siemens 5SU1354-6KV10 FI/LS Protector, Type A, 30mA, 10kA, B","metaDescription":"Siemens 5SU1354-6KV10 FI/LS protector, Type A (PSE/SSF), 30mA, 10kA, 1+N-pole B 10A.

Type A is required on circuits with single-phase rectified loads; Type AC is limited to purely resistive or inductive AC loads without electronics."},{"question":"Where can I buy 5SU1354-6KV10 and get current pricing?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
