The 15 kA interrupting capacity at 230 VAC (10 kA at 500 VDC) tells you it can safely break a fault up to that level without welding the contacts or cascading failure upstream in the panel. The 4-pole format occupies four module widths, so factor that into your enclosure fill count. Rated for 230 VAC phase-to-phase or 500 VDC circuits; the DC interrupt rating at 10 kA makes it suitable for battery banks or DC bus protection in drive cabinets.","metaTitle":"ABB S804C-D16 MCB S800C 4P D 16 A, 15 kA","metaDescription":"ABB S804C-D16 S800C series MCB, 4-pole, Trip Curve D, 16 A, 230 VAC / 500 VDC, 15 kA interrupting capacity.

It also offers a higher 50 kA interrupting capacity at 230 VAC. If your load inrush is moderate (general distribution, resistive or light inductive loads), the S804S-C16 drops into the same panel without rewiring. For motor or transformer circuits where high inrush is expected, stay with the Curve D of the S804C-D16."},{"question":"Where can I buy S804C-D16 and how is it quoted?","answer":"Sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time."},{"question":"Will S804C-D16 drop into a panel specified around S804S-C16 without rewiring?","answer":"Yes, both are 4-pole DIN-rail breakers with the same physical footprint. The swap requires no wiring changes — the difference is the trip curve. Verify the load inrush characteristics before substituting Curve C for Curve D."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S804C-D16","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/abb/S804C-D16 when reusing this data.
