The numbering of the Clauses in this Part corresponds to like nwnbered Clauses in Part 1. The requirements of Part I apply unless modified by this Part. For Clauses not shown below, refer to the Standard for Low-Voltage Fuses - Part 1: General Requirements, NMX-J-009i24&15-2000-ANCE • CSA C22.2 No. 248.1. UL 248-1.
1.1 Scope
This Part applies to Class T fuses rated 1200 A or less and 300 V ac, 800 A or less and 600 V ac. DC ratings are optional.
4 Classification
Class T fuses are non-renewable and current limiting with an interrupting rating of 200,000 A. 300 V ac
Class T fuses are divided into eight body sizes. 600 V ac Class T fuses are divided into seven body sizes.
The maximum current rating In for each size is specified in this Part. Time-delay ratings are optional.
5 Characteristics
5.2 Voltage rating
For AC, the rating shall be 300 V ac or 600 V ac in accordance with dimensions shown in Figures A and
The DC voltage rating may be different from the AC rating.
5.3 Current rating
Refer to Figure A for range of current ratings in each body size for each voltage rating.
5.5 InterruptIng rating
For AC —200,000 A
For DC, the preferred ratings are 10,000, 20,000, 50.000, 100,000, 150,000, or 200,000 A.
