The 10 kA breaking capacity is certified per both EN 60898 (household / commercial standard) and IEC 60947-2 (industrial standard), so it can safely interrupt a fault current up to 10,000 A without welding its contacts or cascading damage upstream. At 63 A and 415 V, this is a main or heavy-feeder breaker in a 3-phase panel, not a branch-circuit device for lighting or general-purpose receptacles. The 5SL7363-8RC occupies 3 modular width units (18 mm per unit, 54 mm total) and installs on a standard DIN rail. Mounting position is unrestricted — vertical, horizontal, or inverted — which simplifies layout in a crowded enclosure. The IP20 rating (with connected conductors) means it is protected against solid objects larger than 12.5 mm but not against moisture; it belongs inside a panel with a sealed door, not in a washdown zone. The breaker is sealable, meaning the toggle can be locked in the off position with a padlock for lockout/tagout. Mechanical service life is 10,000 operating cycles typical; power loss per pole at rated current in hot state is 5.1 W — factor that into thermal calculations for a multi-breaker enclosure.","metaTitle":"Siemens Betagard 5SL7363-8RC MCB, 3P D 63 A, 10 kA, 415 V AC","metaDescription":"Siemens Betagard 5SL7363-8RC miniature circuit breaker, 3-pole, D-curve, 63 A, 10 kA breaking capacity per EN 60898 & IEC 60947-2, 415 V AC.

It is designed for loads with high inrush — motors, transformers, welding machines — where a C-curve would nuisance-trip on startup."},{"question":"Where can I buy the 5SL7363-8RC?","answer":"We source this part to order against an RFQ through independent distribution.

Depth (76 mm) and installation depth (70 mm) are also identical. The DIN-rail clip and terminal layout are the same Betagard/SENTRON family. It will drop in without rewiring or panel modification, provided the D-curve and 63 A rating match the circuit requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL7363-8RC","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/5SL7363-8RC when reusing this data.
