The Type A designation means it detects pulsating DC fault currents in addition to sinusoidal AC — essential on circuits with single-phase rectifiers, switched-mode power supplies, or variable-speed drives where a pure AC-sensitive RCD would be blind to half-wave faults. The 10 mA trip threshold (IΔn) is the highest-sensitivity standard rating; it protects against lethal shock in wet or medical-adjacent zones where 30 mA would be too coarse. The 70 mm depth (D=70mm) is the standard for Siemens 5SU series RCBOs — it sits flush in a DIN-rail enclosure without protruding past the gland plate. The 1+N-pole format occupies a single module width on the rail, leaving adjacent slots free for additional circuits or auxiliary contact blocks. Spring-cage terminals accept 0.2–2.5 mm² solid or ferruled stranded conductors; strip length of 8 mm avoids whiskers under the cage.","metaTitle":"Siemens 5SU1156-7KV06 FI/LS Protector Type A, 10mA, 6kA, 1+N","metaDescription":"Siemens 5SU1156-7KV06 FI/LS-protector Type A, 10mA sensitivity, 6kA breaking capacity, 1+N-pole C-curve 6A.
