1 General
NOTE –
This Part is intended to be read together with the Standard for Low-Voltage Fuses – Part 1:General Requirements, hereafterreferred to as Part 1. The numbering of the Clauses in this Part corresponds to like numbered Clauses in Part 1.The requirementsof Part 1 apply unless modilied by this Part.For Clauses not shown below, refer to the Slandard for Low-Voltage Fuses – Part 1:General Requirements，NMX-J-009/248/15-2000-ANCE CAN/CSA C22,2 No.248.1 UL248-1.
1.1 Scope
This Part applies to Class T fuses rated 1200 A or less and 300 or 60o 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.Each of thevoltage ratins, 300 and 600 V ac, is divided into eight body sizes. The maximum current rating l, for eachsize 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 andB.
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
