Product details

The ABB S804S-D25 is a 4-pole miniature circuit breaker from the S800S series, rated for 25 A continuous current with a Trip Curve D characteristic at 230 VAC.

Trip Curve D and deployment context

Trip Curve D provides magnetic trip between 10× and 20× In (250–500 A instantaneous), sized for loads with high inrush current — motor starters, transformer primaries, welding equipment, or large capacitor banks. On a DIN-rail panel, the 4-pole format occupies four module widths; verify that the enclosure fill factor and thermal derating at elevated ambient temperatures stay within the S800S published limits.

Frequently asked questions

What is S804S-D25's interrupting capacity?

50 kA at 230 VAC, which qualifies it for high-fault installations where standard 10 kA MCBs would not hold coordination.

Where can I buy S804S-D25?

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

What type of loads is Trip Curve D suited for?

Loads with high inrush current — motor starters, transformer primaries, welding equipment, or large capacitor banks — where the magnetic trip point between 10× and 20× In prevents nuisance tripping.
