Product details

The S802S-B25 is a 2-pole miniature circuit breaker rated 25 A with Trip Curve B characteristic, meaning it trips between 3 and 5 times rated current — designed for resistive and lighting loads where inrush is low, not motor starting. The 2-pole form factor means it switches both line and neutral on a single-phase circuit, or two phases in a split-phase system — common for lighting sub-circuits or small distribution boards.

Compliance documentation

As a current-production ABB High Performance MCB, the S802S-B25 carries the usual compliance package — CE marking for the European market, RoHS and REACH declarations for material restrictions, and UL/IEC 60947-2 certification for overcurrent protection. The specific certificate numbers and declaration documents are provided with the shipment or on request.

Frequently asked questions

Who supplies S802S-B25 and how is it quoted for volume purchases?

The S802S-B25 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will S802S-B25 drop into a panel that was specified around S202M-B10 without rewiring?

Mechanically yes — both are 2-pole DIN-rail breakers with the same mounting footprint. Electrically no: the S802S-B25 draws 25 A versus 10 A, and its 50 kA interrupting rating is far higher than the S202M-B10's 6 kA. The panel's bus bar, conductor sizing, and upstream protection must be rated for the higher load and fault current.
