Technical Specifications
Detailed engineering parameters based on manufacturer documentation
| Parameter | Value | Parameter | Value |
|---|---|---|---|
Note | The current is determined by the fuse used, the voltage by the fuse or selected light indicator.
When using fuse terminal blocks in a compound arrangement, the D-UT 2,5/4-TWIN end cover (3047141) must be inserted at each fuse terminal block or a UT 2,5-MTS-EX terminal block (1277636) must be used between each fuse terminal block.
When using partition plates between the fuse terminal blocks, FBS bridges cannot be used due to the separation. | Product type | Fuse terminal block |
