CLASS 1 DIVISION 2 FUSE TERMINAL
Emphatec has partnered with Unibloc to offer a small selection of terminal blocks. These are intended as accessories to Emphatec’s dc power supplies but are also suited for general purpose use as well as Class 1 Division 2 applications. The BC2.5/4 is a 5 mm wide feedthrough terminal while the BC4S is a 6 mm wide lever disconnect terminal. The BC5F is a 5 x 20 mm fuse holder and is 8 mm wide.
All three terminals accept Weidmuller’s Multicard marking tags. Accessories such as partitions and jumper combs are available. The combifoot design allows a single terminal to be used on any of the commonly available DIN rails – 15 mm, 32 mm, 35 x 7.5 mm and 35 x 15 mm.
For Class 1 Division 2 applications the terminals have been tested for temperature rise and pull-out. The pull-out tests are not only for the wire terminations but are also performed on the fuse lever. The lever must withstand a force of 15 N to ensure it cannot be accidentally operated while under load and cause an arc. Generally only screw-in style fuse terminals would meet this requirement but the BC5F passes easily.
