| Notes | General 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-UT2,5/4-TWIN end cover (3047141) must be inserted at each fuse terminal block or a UT2,5-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. |
