Product details

The ABB S804C-D16 is a 4-pole miniature circuit breaker from the S800C series, rated 16 A with Trip Curve D. 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.

Frequently asked questions

What is the closest functional second-source to S804C-D16?

The S804S-C16 shares the same 16 A, 4-pole, DIN-rail footprint but uses Trip Curve C (magnetic trip at 5–10× In) instead of Curve D. 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.

Where can I buy S804C-D16 and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.

Will S804C-D16 drop into a panel specified around S804S-C16 without rewiring?

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.
