Fuse terminal blocks with screw connection from the SNA series are available in widths from 8 mm to 13 mm. They enable simplified wiring of alternating through and fuse circuits and also offer the option of user-friendly testing with test sockets already installed. ABB's screw connection technology was developed to prevent the connections from coming loose due to vibrations, impacts or even accidental pulling on the cable. Thanks to the exclusive design, re-tightening the connections is no longer necessary in every case. They cover a connection requirement of 0.22 mm to 240 mm. The screw connection technology allows up to two conductors to be connected per terminal, thus ensuring more flexibility in the control cabinet. Simple cable routing, as the conical opening guides the conductor precisely into the terminal cage.
