WTR "Old Style" Disconnect Terminal Block
Change in Design
Weidmuller introduced the ZQV pluggable jumpers (or cross-connection) for the WDU 2.5 series of terminal blocks to provide fast and reliable jumpering. This system was an instant success. Users wanted the same exceptional functionality for the WTR disconnect blocks.
Weidmuller responded by introducing a new design for the WTR. The new design features a smaller disconnect lever plus a slot for the insertion of the ZQV 2.5 series pluggable jumpers. The basic part number for this terminal block (wihout test sockets) is P/N 1855610000.
