Transformer Protection

(OP)
I'm looking for the 'K' factor for a S&C SMU-20 fuse link.  At one of my rural substations I'm using 65E (Slow) fuses for my high side protection and 3 single phase 50A type E hydraulic reclosures (1A-3B)on the low side for feeder protection.  I've been using page 111 of my Cooper "Electical Distribution-System Protection" book to establish the 'K' factor and coordination for T-link fuse-reclosure coordination and was wondering if there is any literature on S&C's silver/E-type fuses...
Please advise...

RE: Transformer Protection

You may have to contact the respective manufacturer's manual for it.
