DC Connector

IEC TR 63225:2019 highlights the problem of incompatibility of connectors for DC-application in photovoltaic systems (DC connectors) produced by different manufacturers. It addresses four particular issues in that context: - background information on incompatibility of DC connectors from different manufacturers; - observations and challenges concerning the handling of DC connectors from different manufacturers; - stakeholders concerned by the incompatibility of DC connectors; - recommendations for long-term standardization and interim measures to address incompatibility of DC connectors.

IEC 62852:2014+A1:2020 applies to connectors for use in the d.c. circuits of photovoltaic systems according to class II of IEC 61140:2001 with rated voltages up to 1 500 V d.c. and rated currents up to 125 A per contact. It applies to connectors without breaking capacity but which might be engaged and disengaged under voltage. This consolidated version consists of the first edition (2014) and its amendment 1 (2020). Therefore, no need to order amendment in addition to this publication.
