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.","metaTitle":"ABB 2CDS272061R0337 MCB, K Curve, 4 A, 2-Pole, 10 kA","metaDescription":"ABB 2CDS272061R0337 miniature circuit breaker, K characteristic, 4 A rated current, 2-pole, 440 V, 10 kA Icn, 25 kA Icu.

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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/2CDS272061R0337","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/abb/2CDS272061R0337 when reusing this data.
