Product details

The K curve means it trips between 8 and 12 times rated current, designed for inductive loads like motor circuits, transformers, and solenoid valves where inrush current is higher than a resistive load but lower than a pure motor-start.

Breaking capacity — what the two numbers mean

Rated short-circuit breaking capacity Icn is 10 kA per IEC 60898 — that's the service breaking capacity for general distribution. For a 4 A K-curve MCB, that's a wide safety margin in a panel fed by a transformer with moderate fault current.

IP20 finger-safe on the front face; IP40 inside the enclosure once installed. The 35 mm width per pole means a 2-pole unit takes 70 mm of DIN rail space. Depth of 69 mm and height of 88 mm fit standard distribution boards without crowding the gland plate.

Frequently asked questions

What is the K tripping curve for this breaker?

The K characteristic trips at 8 to 12 times rated current (32 A to 48 A for this 4 A unit). It's intended for inductive loads — motor circuits, transformers, solenoid valves — where the inrush is higher than a resistive load but lower than a pure motor-start D-curve would handle.

Where can I buy the 2CDS272061R0337?

This part is 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 published here.

What is the difference between Icn and Icu on this breaker?

Icn (10 kA) is the service breaking capacity per IEC 60898 — the breaker can clear that fault repeatedly in normal service. Icu (25 kA) per IEC 60947-2 is the ultimate breaking capacity for industrial use — it clears a 25 kA fault once and remains functional afterward. The Icu rating gives you a higher safety margin in industrial panels.
