Motor Fuse Links
Higher Current Ratings
Higher ratings than those tabulated above can be obtained by using fuse links connected in parallel. Special fixing arrangements for
connecting up to 3 fuse links in parallel, are available. Please contact Bussmann application engineers for more details. The code
designations for these arrangements are given in ‘How to Order’ (page 61), dimensional drawings are given on page 26.
