The 70 mm width (four modules) is wider than a standard single-pole MCB because the RCBO packs both the RCD coil and the breaker mechanism in one housing. Neutral is factory-connected through the solid bar on the N-pole side — no separate neutral link needed downstream. Rated for use in TN, TT, and IT earthing systems per IEC 60898-1.","metaTitle":"Siemens 5SU1156-7KV13 FI/LS Protector Type A, 10mA, 6kA, C 1","metaDescription":"Siemens 5SU1156-7KV13 FI/LS protector Type A (PSE/SSF), 70mm, 10mA IΔn, 6kA breaking capacity, 1+N-pole C-curve 13A.

Type A means it detects both sinusoidal AC residual currents and pulsating DC residuals, which covers modern electronics with half-wave rectification. PSE/SSF are internal Siemens designations for the product family and form factor."},{"question":"What is the breaking capacity of this RCBO?","answer":"The 5SU1156-7KV13 is rated for 6 kA breaking capacity per IEC 60898-1, which is the standard level for residential and light-commercial final circuits."},{"question":"Where can I buy the 5SU1156-7KV13 and get current pricing?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution channels.
