Schurter KFA is a power entry module with line filter, offering 1 or 2 fuseholders, with or without voltage selector.
The KFA power entry module with line filter is a panel‑mount component that can be installed as snap‑in or screw‑on from the front side. It offers four functions: inlet protection, fuseholder for 5 × 20 mm fuse‑links, optional voltage selector, and a line filter available in standard and medical versions.
Technical data include rated currents, leakage current limits, dielectric strength, operating temperature range, and protection class. Various order numbers define the rated current, mounting type, pole count and whether a voltage selector is included. Accessories such as fuse drawers and cord‑retaining kits are also listed.
