Why should you use BS EN IEC 60320‑2‑4?
Appliance coupler have the tendency for enabling the connection and disconnection, of a cord to an appliance or other equipment. It consists of two parts: a connector and an appliance inlet.
Weight-engaged coupler is a coupler that relies on the weight of the functioning part of the appliance, in which it is incorporated or integrated, to ensure correct engagement.
BS EN IEC 60320‑2‑4 provides you the instructions for installing weight engaged couplers which contains necessary information to ensure the compliance and contain the classification declared by the manufacture.
BS EN IEC 60320‑2‑4 helps you ensure resistance and protection for couplers against electric shock, moisture, insulation, heat and ageing.
As a buyer of BS EN IEC 60320‑2‑4, you will be able to acquire a better quality of couplers for weight-engagement with all safety and testing applied.
What’s changed since the last update?
BS EN IEC 60320‑2‑4:2021 supersedes BS EN 60320‑2‑4:2006+A1:2009, which will be withdrawn on 19 March 2024.
