SCHURTER KMF protection class II power entry module

SCHURTER has expanded its range of power entry modules to include versions without ground pin for use in protection class II double-insulated applications. Its protection class II version is suitable for use in medical equipment according to the IEC standard 60601-1-11, which outlines safety measures specific to medical equipment intended for use in the home.

Protection class II equipment generally has no metal case. It is double insulated and requires higher safety levels for energised components relative to exposed surfaces. The KMF class II power entry module provides double insulation between energised components and exposed parts. This reinforced insulation is tested with a voltage of 4000 VDC between the energised conductor and the neutral conductor relative to the mounting panel.

The product is available with a 2-pole line switch and a 1- or 2-pole fuse holder. For medical applications, an extra-safe fuse holder is available that can only be opened with the aid of a tool. An EMC filter is available in medical and low-leakage versions. The integrated filter at the power input provides effective interference suppression, which results in optimised electromagnetic compatibility.

Current ratings range from 1–10 A at 250 VAC and connections take place with quick-connect terminals 4.8 x 0.8 mm. The product is rated according to IEC 60320-1, style C18 and is ENEC, cURus and CCC approved.
