Product details

16 A, Curve K — what it means for the panel

Curve K is designed for motor and inductive load protection — it holds through the inrush of a motor start (typically 8–12× rated current) while still tripping fast on a hard short. For a 16 A breaker, that means it can ride out the starting surge of a small motor or transformer without nuisance tripping, something a Curve C or B breaker at the same current might not do. The 2-pole configuration suits single-phase or two-leg protection in a 230/400 V distribution panel.

Frequently asked questions

Where can I buy S272-K16?

The S272-K16 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is S272-K16's listed amps and trip curve?

The S272-K16 is rated at 16 A with a Trip Curve K characteristic, designed for motor and inductive load protection where inrush currents are expected.

Will S272-K16 drop into a panel specified around S202M-C16 without rewiring?

Both the S272-K16 and S202M-C16 are 2-pole DIN rail miniature circuit breakers at 16 A, so the physical footprint and mounting are the same. However, the S272-K16 uses Trip Curve K (motor/inductive protection) while the S202M-C16 uses Trip Curve C (general-purpose protection). The trip characteristic differs — Curve K holds through higher inrush before tripping. If the original design relied on Curve C's faster magnetic trip for coordination, swapping to Curve K may change selectivity. Check the coordination study before substituting.
