Rated 20 A at 30 °C ambient, this RCBO derates linearly as the panel temperature climbs: 18.8 A at 40 °C, 17.4 A at 50 °C, 15.4 A at 65 °C, and 14.6 A at 70 °C. If your distribution board sits in a hot mechanical room or next to a furnace, the 30 °C figure is not the one you spec against — use the 50 °C or 65 °C column. The breaking capacity is 10 kA per EN 60898 (the standard for household-type MCBs) and 20 kA per IEC 60947-2 (the industrial standard) — so it handles fault currents up to 20 kA in an industrial panel where the prospective short-circuit current is higher. The unit is halogen-free and silicon-free — relevant for semiconductor fabs, clean rooms, or any environment where outgassing from a fault event must not corrode nearby contacts or optics. Two modular-width units (36 mm) snap onto standard DIN rail. Depth is 77 mm, installation depth 70 mm — check your enclosure depth before committing the BOM; a shallow 80 mm enclosure leaves only 3 mm clearance behind the device. Rated IP20 with conductors connected and distribution board installed — this is a panel-internal device, not for standalone outdoor use without an enclosure.","metaTitle":"Siemens 5SU1354-6KK20 SENTRON RCBO, B-Curve 20 A, 10 kA","metaDescription":"Siemens 5SU1354-6KK20 SENTRON RCBO, 1P+N, B-curve, 20 A at 30 °C, 10 kA per EN 60898. 2-module width, halogen-free.

The 5SU1354-6KK20 is a B-curve 20 A unit; the 5SU9354-7KK16 carries a different rating or curve. They share the same 2-module DIN-rail footprint and 1P+N pole design, so a panel laid out for one will physically accept the other without rewiring the busbar or neutral bar, but the protection settings differ — verify the curve and amp rating against your circuit's load and fault requirements before swapping."},{"question":"Where can I buy the 5SU1354-6KK20?","answer":"This RCBO is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commitment."},{"question":"What compliance documentation does Siemens provide for the 5SU1354-6KK20?","answer":"The unit is halogen-free and silicon-free, which supports RoHS and REACH compliance declarations. It is rated per EN 60898 and IEC 60947-2, and carries overvoltage category III and pollution degree 2 ratings. For specific UL, CE, or UKCA declarations, the manufacturer's documentation set covers these standards for the SENTRON series."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU1354-6KK20","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/5SU1354-6KK20 when reusing this data.
