ST 4-MT Knife Disconnect Terminal Blocks 400V DIN Rail NS 35

The Spring Cage Knife Disconnect Terminal Blocks are designed to facilitate testing and maintenance procedures, allowing for quick and easy localization of malfunctions. These terminal blocks are equipped with test socket screws, which enable the insertion of test plugs for convenient testing purposes. The lever-type disconnect knife provides a convenient way to separate circuits when needed, whether it's for isolating a specific section or for using an isolating plug or rotary contact. The terminal blocks are designed to be user-friendly, allowing for current measurement on either side of the disconnect point, ensuring accurate and efficient testing procedures. Safety is prioritized in the design, as the disconnect lever is locked in the end positions, preventing accidental disconnection or improper operation. The terminal blocks offer flexibility in assembly, allowing for individual configuration with disconnect elements, fuse plugs, component connectors, and feed-through connectors as required for specific applications.
