Four-pole design (3P+N) covers three-phase systems with neutral — the neutral pole switches and is monitored for residual current. The 10 000 mechanical operating cycles typical service life suits it for distribution panels where switching is infrequent (quarterly test / maintenance cycles), not daily load-break duty. ## DIN-rail fit and enclosure integration Depth is 70 mm, installation depth also 70 mm, so it sits flush with the DIN rail edge; no extra rear clearance needed beyond the rail itself. Height is 90 mm. IP20 with connected conductors — the terminals are finger-safe only when the distribution board is closed; treat it as an enclosed-panel device, not a standalone outdoor unit. Supply can land top or bottom — no mandatory orientation for line/load. The test circuit requires minimum 100 V to operate, so it functions on 230/400 V systems without a separate test supply. Silicon-free construction, overvoltage category III, ambient range -25 °C to +45 °C. Storage range extends to -40 °C.","metaTitle":"Siemens 5SV3644-6KK01 RCCB, 40 A, 300 mA, 4-pole, Type A","metaDescription":"Siemens SENTRON 5SV3644-6KK01 RCCB, 4-pole type A short-time delayed, 40 A rated current, 300 mA residual, 400 V AC.

The RCCB provides both isolation (4-pole switching) and earth leakage protection. However, it does not provide overcurrent protection — the upstream MCB or fuse must coordinate to clear overloads and short-circuits. The short-time delayed characteristic helps with selectivity against downstream RCCBs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SV3644-6KK01","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/5SV3644-6KK01 when reusing this data.
