Introduction

In order to standardize the energy efficiency measurement and testing of AC contactors implementing energy efficiency labeling management, this specification is formulated in accordance with the requirements of JJF 1261.1-2017 "Energy Efficiency Measurement and Detection Rules for Energy-using Products".

This specification replaces JJF 1261.18-2015, compared with JJF 1261.18-2015, except for editorial changes.

The main changes are as follows.

--- The name of the specification was changed from "Regulations for the measurement of AC contactor energy efficiency labels" to "AC contactor energy sources "Efficiency measurement detection rules";

--- "5.1 Energy efficiency labeling" adds "energy efficiency information code" and "energy efficiency 'leader' information" Etc.

--- The original record format and report format were modified accordingly (Appendix C, Appendix D) the previous versions of this specification were issued as follows.

---JJF 1261.18-2015.

AC contactor energy efficiency Metering detection rules

1 Scope

This specification specifies the rated frequency of 50Hz, rated operating voltage of 380V (400V), rated operating current 6A ~ 630A direct-acting, three-electromechanical, control circuit input power for the exchange of the overall AC contactor Energy efficiency measurement requirements, metrological testing procedures, metrology testing methods, criteria for the assessment of metrological test results, and test reports Say something.

This specification does not apply to additional energy-saving devices, household and similar contactors and semiconductor contactors (Solid State Connections) Toucher).

This specification applies to the measurement and supervision of the energy efficiency measurement of AC contactors. The commissioned inspection can be conducted with reference to this specification. Students Units that produce and sell AC contactor products may also be tested in accordance with this specification.

The AC contactor that is tested shall be the product that the manufacturer has passed the inspection, or it is imported and sold by the seller.

commodity.

4 Overview

AC contactors are energy-using products that implement energy efficiency label management. AC contactor is a type used to connect frequently the electrical equipments that pass and break the AC main circuit and the large-capacity control circuit mainly include a contact system, an electromagnetic mechanism, and an arc extinguishing device.
