It integrates Type A residual current detection at 300 mA with a 1+N-pole thermal-magnetic overcurrent trip characteristic C rated at 20 A, all in a 70 mm wide housing. The 70 mm module width (4 TE on a standard DIN rail) occupies four 18 mm pitch units in the distribution board. Plan for this when laying out multi-pole RCBO combinations in a crowded enclosure — the 1+N-pole format saves one module width versus a 2-pole device for the same single-phase protection scheme.","metaTitle":"Siemens 5SU1654-7KV20 FI/LS Protector, Type A, 300mA, 10kA,","metaDescription":"Siemens 5SU1654-7KV20 FI/LS protector, Type A, 300mA residual current, 10kA breaking capacity, 1+N-pole C 20A.

The 300 mA sensitivity is the standard for fire protection in many European installation standards — it allows for leakage from long cable runs and equipment filters without nuisance tripping, while still providing arc-fault protection."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU1654-7KV20","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/5SU1654-7KV20 when reusing this data.
