Having had to dig around a bit to find the fuse types for the three Alphapack versions, I'm documenting here for other users:   All fuses are 6.3A, ceramic HRC fast acting, 5x20mm.   Alphapack1: 5x20mm (Note: NOT 32mm as quoted in this datasheet: http://zero88.com/support/index.php?/Knowledgebase/Article/GetAttachment/266/264)   Alphapack2: 5x20mm (http://zero88.com/support/index.php?/Knowledgebase/Article/GetAttachment/84/616)   Alphapack3: 5x20mm (http://zero88.com/datasheets/Alphapack_3_Datasheet_UK_Rev2_0516.pdf)   5x20mm: RS 563-330 http://uk.rs-online.com/web/p/cartridge-fuses/0563330/ CPC FF02830 (SIBA 70-007-33/6.3A) http://cpc.farnell.com/siba/70-007-33-6-3a/fuse-20x5-ceramic-quick-blow-6/dp/FF02830
