IEC C20 mains filter inlet snaps in for fast assembly

Author: EIS Release Date: Jun 20, 2022

Schurter has created snap-in filtered IEC C20 mains inlet connectors to speed up assembly.

 

Part of the company’s EC12 filter series, they include a single-stage filter and power switch.

 

Instead of the screw flange, they have two snap-in springs. “Thanks to the high-quality springs, a tight-fitting installation is ensured with good electrical contacting of the mounting panel at the same time,” said Schurter. “The wide metal flange contacts the housing over a large surface area, enabling optimum filtering and shielding effect.”

 

Panels from 1mm to 3mm thick can be accommodated, and the cutout is ~48 x 34mm with radiused corners.

There are two filter versions: standard (diagram left) or medical (without Y-capacitors) allowing IT or telecom systems to be accommodated to IEC 92368-1 or medical equipment to IEC 60601-1. “For applications according IEC/UL 62368-1, we recommend variants with bleed resistor,” said the company.

 

Current is up to 16A/250Vac according to IEC, and 20A according to UL/CSA at 125/250Vac.

 

For increased surge withstand voltage, there are versions that have safety class X1 interference suppression capacitors that can cope with 4kV surges between L and N, and Y1 caps for surges of 8kV.

 

The parts come with ENEC, CQC and cURus approvals.
