Product details

The K curve is specifically designed for DC applications and inductive loads — it holds through moderate inrush without nuisance tripping, then clears fast on hard faults. This is the curve to reach for when protecting DC motor circuits, solenoid valves, or control transformers where a C curve might trip on startup current and a Z curve would be too slow on a dead short.

The Trip Curve K means magnetic trip occurs at 8–12× rated current (32–48 A), which is higher than a C curve (5–10×) but lower than a D curve (10–20×).

Frequently asked questions

What is the S201DC-K4 used for?

It protects DC circuits up to 60 V and AC circuits at the same voltage, with a Trip Curve K that handles inductive loads like DC motor starters, solenoid valves, and control transformers without nuisance tripping on inrush.

Where can I buy the S201DC-K4?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What does the 10 kA interrupting rating mean?

It means the breaker can safely interrupt a fault current up to 10,000 A at 60 V DC without failing, which is adequate for most control panel DC bus applications.
