Popis
BS EN 60644:2009+A1:2019
This standard BS EN 60644:2009+A1:2019 Specification for high-voltage fuse-links for motor circuit applications is classified in these ICS categories:
- 29.120.50 Fuses and other overcurrent protection devices
This document applies to fuse-links complying with IEC 60282‑1 that are used with motors started direct-on-line on alternating current systems of 50 Hz and 60 Hz.
Fuse-links according to this document are intended to withstand normal service conditions and motor starting pulses.
The purpose of this document is to standardize time-current characteristics and to formulate pulse withstand requirements regarding testing.
This document also applies to fuse-links used with motors that use assisted starting when appropriate care has been taken with selecting the rated current of the fuse-link (using advice from 5.2.3 of IEC TR 62655:2013 and from the fuse manufacturer).
