Two Test Slots

With the new 221 Series Splicing Connectors, you can now test the voltage from two different sides – even when installed. The connectors carry two test slots right where the WAGO imprint is shown: one in the conductor entry direction and one on the opposite side. This accessibility provides extremely convenient testing conditions – even after installation within a wide range of applications. All connector variants also provide a secure contact for all standard test probes.
