Product details

The K-curve means magnetic trip occurs between 8 and 12 times rated current (32–48 A), making it suitable for loads with moderate inrush — motor starters, transformers, or solenoid valves common in tire-curing press control cabinets where steam valves and hydraulic solenoids draw a brief surge. Snap it onto a DIN rail in the panel — 17.5 mm wide, standard 1-module footprint.

The 17.5 mm width leaves room for adjacent modules in a crowded enclosure. The black actuator is sealable and carries I/O marking for lockout/tagout. Strip length for the screw terminals is standard for the class; torque to the value printed on the device face.

Frequently asked questions

Where can I buy S201P-K4 and how is it quoted?

The S201P-K4 is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What is S201P-K4's listed amps and trip curve?

Rated 4 A continuous with a K-curve trip characteristic — magnetic trip between 32 and 48 A (8–12x In), thermal trip at 4.2 A.

Will S201P-K4 drop into a panel specified around S201M-C3?

Both are 1-pole DIN-rail breakers in the same S200 family, so the footprint and busbar connection are identical. The difference is the trip curve: S201M-C3 is a C-curve (magnetic trip 5–10x In) at 3 A; the S201P-K4 is a K-curve at 4 A. If the panel's load and coordination study call for a K-curve at 4 A, the S201P-K4 is the correct fit — it will not drop in as a direct substitute for a C-curve without verifying the upstream selectivity.
