Product details

Rated 6 A at 30 °C and 230 V AC, with a breaking capacity of 6 kA per EN 60898. At 40 °C the continuous rating derates to 5.53 A; at 50 °C it drops to 5.02 A. If the panel ambient runs warm, size up one frame or account for the thermal curve.

Mounting position is unrestricted. The neutral conductor is switched internally — no separate neutral bar needed downstream. Touch protection is provided. Sealable for tamper-evident installations. Halogen-free and silicon-free materials matter for environments sensitive to outgassing, such as clean rooms or sealed enclosures.

Compliance and approvals

Rated according to EN 60898. Overvoltage category III, pollution degree 2. Protection class IP20 with connected conductors. The product designation follows EN 61346-2 and IEC 81346-2 function code F.
