The short-time delay (Type F) means it tolerates brief high-frequency leakage pulses from variable-speed drives or UPS equipment without nuisance tripping — a common need on modern lines with VFD-fed motors. Snaps onto DIN rail (REG) — standard 35 mm profile. Depth is 70 mm, same as the installation depth, so it sits flush with the front edge of a standard distribution board. The IP20 rating applies once the distribution board is installed with conductors connected; that's typical for enclosed panel gear, not for open-chassis use. The 300 mA residual sensitivity is a higher threshold than the standard 30 mA, chosen for equipment protection or where leakage from drives would trip a more sensitive unit. The short-time delay (Type F per IEC 61008-1) gives it a 0.8 kA rated conditional short-circuit current according to that standard, and the 10 kA SCCR covers the fault-clearing capability per IEC 60947-2.","metaTitle":"Siemens 5SV3646-3 SENTRON RCCB, 4P, 63A, 300mA, Type F","metaDescription":"Siemens 5SV3646-3 SENTRON RCCB, 4-pole Type F, 63 A, 300 mA, 10 kA SCCR, short-time delayed.

A standard 30 mA RCCB would nuisance-trip on those waveforms. The 300 mA threshold also suits equipment protection rather than personnel shock protection."},{"question":"Does the 5SV3646-3 fit in a panel designed for a 5SL4363-7 MCB?","answer":"No — the 5SV3646-3 is 4-pole, 72 mm wide (4 MW), while the 5SL4363-7 is a 3-pole MCB at 54 mm (3 MW). The depth is similar (70 mm vs 76 mm), but the width and pole count differ. You'd need to re-space the DIN rail and re-feed the neutral through the fourth pole."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SV3646-3","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/5SV3646-3 when reusing this data.
