Test terminal blocks
Weidmuller’s test terminal blocks provide companies in the process industry the ability to bring “common” circuits together to perform measurement and testing for quick failure detection. The WTR terminals feature screw connection technology and are available in WTR 4/ZR-Branch, or WTR 4/ZZ-dual connections on both sides. These space-saving designs eliminate the need for a second terminal block with jumper accessory. Accessories are offered to extend the use of the WTR 4/ZZ and WTR 4/ZR terminal blocks. The SIHA 3 fuse holder enables the user to easily convert the disconnect terminal to a fuse terminal. The component plug converts the WTR terminals into component terminals with resistors or diodes.
