The 100 mA residual trip is a common choice for equipment protection (not personnel shock protection, which typically uses 30 mA) — it's sized to catch insulation faults on feeders or large loads without nuisance tripping from normal leakage. Depth is 70 mm, same as the installation depth, so it sits flush with the front of a standard distribution board.","metaTitle":"Siemens 5SV4444-0LA SENTRON RCCB, 40 A, 100 mA, 4-Pole, DIN","metaDescription":"Siemens SENTRON 5SV4444-0LA RCCB, 40 A rated, 100 mA trip, 4-pole, 10 kA SCCR.

The 5SV4444-0LA is a residual current device (RCCB) that detects earth leakage but does not provide overcurrent protection. They serve different protection functions and are not direct substitutes; a panel specified for one cannot simply swap in the other without rewiring the protection scheme."},{"question":"What is 5SV4444-0LA's listed depth?","answer":"The depth is 70 mm, which matches the installation depth — it sits flush with the front of a standard distribution board."},{"question":"What conductor sizes does 5SV4444-0LA accept?","answer":"It accepts both solid and stranded conductors from 0.75 mm² up to 35 mm², covering control-circuit tails through main feeder cables."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SV4444-0LA","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/5SV4444-0LA when reusing this data.
