Product details

What the K-curve and 63 A rating mean on site

K-curve breakers are built for inductive loads — motors, transformers, solenoid banks. The magnetic trip threshold sits higher than a B or C curve (typically 8–12× rated current), so it won't nuisance-trip on the inrush of a 63 A-rated motor or a cluster of contactor coils. At 63 A, this 2-pole unit covers a 15–20 kW motor on 277/480 V three-phase, or a pair of 277 V lighting feeds. The 10 kA interrupting rating means it can clear a bolted fault at the panelboard without welding its contacts shut — standard for downstream distribution in a 100 kA-rated main switchboard.

Panel fit

Two-pole width (36 mm nominal) fits a 2-module slot in any ABB or third-party distribution board.

Frequently asked questions

Where can I buy the S202P-K63 and get a price?

The S202P-K63 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What does the 63 A rating mean for this breaker?

The 63 A rating is the continuous current the S202P-K63 carries without tripping. It's the load current the breaker protects — sized for a 15–20 kW motor or a 63 A lighting/distribution feeder on 277 V.

What is the K-curve used for?

The K-curve has a magnetic trip threshold of 8–12× rated current, designed for inductive loads like motors, transformers, and solenoid banks. It resists nuisance tripping on inrush while still providing short-circuit protection.
