It combines Type AC residual-current detection at 30 mA with a C-curve overcurrent trip at 25 A, all rated for a 10 kA short-circuit breaking capacity. The G-type designation indicates a short time delay (typically 10 ms) to coordinate with downstream devices and reduce nuisance tripping on transient surges. The 30 mA sensitivity covers the standard personnel-protection threshold per IEC 60364 — it clears earth faults before they reach a dangerous let-through energy level. The 70 mm width (about 4 module spaces on a DIN rail) is standard for a 1+N RCBO in the Siemens 5SU family, so it slots into any 18 mm-module enclosure without crowding.","metaTitle":"Siemens 5SU1354-1LV25 FI/LS-protector, Type AC, 30 mA, 10 kA","metaDescription":"Siemens 5SU1354-1LV25 FI/LS-protector, Type AC, 30 mA, 10 kA, 1+N-pole, C 25, G-type.

The deciding factor for fit is the C-curve and 25 A rating — if your load inrush matches C-curve, this is the exact spec."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU1354-1LV25","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SU1354-1LV25 when reusing this data.
