Specification for High-Voltage Fuse-Links for Motor Circuit Applications
|Publication Date:||1 January 1979|
|ICS Code (Fuses and other overcurrent protection devices):||29.120.50|
This standard applies primarily to fuse-links used with motors started direct-on-line on alternating current systems of 50 Hz and 60 Hz.
Note. - When motors are used with assigned starting this specification can also be applied but particular attention should be paid to the selection of the rated current of the fuse-link (see Sub-clause 8.1) and the manufacturer of the fuse-link should preferably be consulted.
Fuse-links according to this specification are intended to withstand normal service conditions and motor starting pulses. They shall comply with the requirements of IEC Publication 282-1: High-voltage Fuses. Part 1: Current-limiting Fuses.
