Datasheet

The KMF power entry module from Schurter is for use in protection class II double-insulated applications and is now in stock at distributor Rutronik. It provides high functionality in a compact package, just like the popular module for use in protection class I. The new version is suited for medical equipment used at home.

Protection class II equipment, in contrast to protection class I equipment, generally has no metal case. This category of equipment is called double insulated, and requires higher safety levels for energized 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 4000VDC between the energised conductor (L) and the neutral conductor (N) relative to the mounting panel.

The new KMF class II version without ground pin has been designed to meet IEC 60320-1, style C18. The KMF line switch 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. The EMC filter is obtainable in medical and low leakage, M5, versions.

This integrated filter at the power input provides highly effective interference suppression, which results in optimized electromagnetic compatibility.

Current ratings range from 1-10A at 250VAC. Connections take place with quick-connect terminals 4.8 x 0.8mm.

The KMF class I and class II are ENEC, cURus and CCC approved. They are suited for use in equipment according to IEC 60950 and IEC 60601-1. Furthermore, the class II version is particularly well suited for use in medical equipment according to IEC 60601-1-11, which outlines additional safety measures specific to medical equipment intended for use in the home.
