Product details

25 A, Curve K, 50 kA — what the ratings mean

The ABB S802S-K25 is a 2-pole High Performance Miniature Circuit Breaker rated 25 A at 230 VAC, with a Trip Curve K characteristic and a 50 kA interrupting capacity. Curve K is a magnetic-only trip characteristic with a narrow instantaneous trip band (typically 8–12x In), designed to ride through the inrush of inductive loads like solenoid valves, contactor coils, and small transformers while still providing short-circuit protection. The 25 A continuous rating governs the load it can carry in free air at 30 °C; derate per the manufacturer's thermal curve when ganged or enclosed.

Panel integration

Snap-on DIN rail mounting per EN 60715. The 2-pole footprint occupies two 17.5 mm modular spaces. Spring-cage terminals accept 0.2–25 mm² conductors; strip length 12 mm. Torque to 2.5 Nm. The busbar comb bridges across the line side for a common feed; verify the comb pitch matches the S800 series terminal spacing before ordering.

Frequently asked questions

What is S802S-K25's interrupting rating?

The S802S-K25 has a 50 kA interrupting rating at 230 VAC, which means it can safely interrupt fault currents up to that level.

Where can I buy S802S-K25?

The S802S-K25 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at the time of quotation.

What does Trip Curve K mean on the S802S-K25?

Trip Curve K on the S802S-K25 is a magnetic-only trip characteristic with a narrow instantaneous trip band (typically 8–12x In), designed to ride through the inrush of inductive loads like solenoid valves and small transformers while still providing short-circuit protection.

Will S802S-K25 drop into a panel specified around S202M-B10 without rewiring?

No. The S802S-K25 is a 25 A Curve K breaker with a 50 kA interrupting rating, while the S202M-B10 is a 10 A Curve B breaker with a 6 kA interrupting rating. They are not drop-in substitutes; the panel's fault current rating, load current, and trip coordination must be re-evaluated.
