Product details

Trip curve K provides a magnetic trip threshold of 8 to 12 times the rated current, making it suitable for motor and transformer circuits where inrush currents are higher than resistive loads. The thermal mechanism handles overload protection; the electromechanical mechanism handles short circuits. Rated operational voltage is 400/690 V AC, 375 V DC, at 50/60 Hz. The 230 V AC entry in the spec table reflects a common test voltage; the device is rated for the full 400/690 V AC range per the description.

Integration into your panel

Snap-on DIN rail mounting keeps panel integration straightforward — the 3-pole footprint fits standard 3-module spacing. Rated frequency of 50/60 Hz covers both legacy 50 Hz European installs and 60 Hz North American lines.

Frequently asked questions

What is S803S-K32's interrupting rating?

50 kA at 400 V AC, which covers most industrial distribution panels with high available fault current.

Where can I buy S803S-K32 and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is listed here.

What does trip curve K mean for this breaker?

Magnetic trip between 8 and 12 times rated current (256–384 A), designed for motor and transformer circuits that draw higher inrush without nuisance tripping.
