Breaking capacity — what the ratings mean
Rated 15 kA per EN 60898 at 230 V AC and 40 kA per IEC 60947-2 — the higher figure applies when the breaker is used as an industrial circuit breaker under the product standard, giving headroom for high-fault installations. At DC it handles 15 kA per IEC 60947-2 up to 72 V, and under UL 1077 / CSA C22.2 No. 235 it carries 5 kA at AC.
D-curve — why it matters for your load
The D characteristic trips magnetically between 10× and 20× In (30–60 A for this 3 A unit), so it holds through the starting surge of a small motor or a transformer inrush without nuisance tripping. That makes it a common pick for mechanical engineering and industrial environments where inductive loads dominate.
The terminals are sealable and touch-protected. Strip length is not stated, but the 70 mm installation depth plus 76 mm overall depth leaves room for a standard DIN-rail gland plate.
Halogen-free and silicon-free construction suits sealed enclosures and sensitive electronics environments. IP20 with connected conductors. Overvoltage category III. The lifecycle status is current production.
