The 1way version, list no. 503 Si DS is intended to be interlocked to multi-way connectors 503 Si DS. This way, 2
to 5way connectors can easily be extended by any required no. of fuse holders by simply locking them together.
When clamping fine wires or particularly small conductor sizes, we recommend to use that type with wire
protector, in order to prevent the conductor or single strands from being damaged.
Marking labels to be placed underneath can be supplied either printed or unprinted according to your
