The 10 mA IΔn (rated residual operating current) means it trips on earth leakage as low as 10 mA — that's the sensitivity you'd spec for personal protection in wet or medical-adjacent circuits, not just equipment protection. The C-curve (13 A rated current) handles moderate inrush from motor or lighting loads — it'll hold through a short startup surge without nuisance tripping, unlike a B-curve that would pop on the same load. ## Deployment context The 70 mm depth (D=70MM) is the overall module depth from the rail surface — check your enclosure depth clearance if you're retrofitting into a shallow box. The 1+N-pole format means it switches the line conductor and provides a switched neutral; standard for single-phase final circuits in TN or TT systems where you need both poles isolated.","metaTitle":"Siemens 5SU1154-1KV13 FI/LS Protector, Type AC, 10kA, 13A, 1","metaDescription":"Siemens 5SU1154-1KV13 FI/LS protector, Type AC, 10kA breaking capacity, 13A C-curve, 1+N-pole, 10mA IΔn.

The 10 mA IΔn is the residual trip sensitivity — it protects against earth faults down to that level. The 10 kA is the short-circuit breaking capacity. The C-curve at 13 A means it tolerates moderate inrush currents typical of lighting or small motor loads. Type AC means it detects sinusoidal AC residual currents only, not pulsating DC or smooth DC — important if your load includes half-wave rectifiers or variable-speed drives."},{"question":"Where can I buy 5SU1154-1KV13 and how do I get pricing?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
