Tender specification sheets

Long specification
Feed-through terminal, 12.4mm wide with varistor arrester between the signal line connection and the mounting rail potential, TS 35 contact base.A signal with max. 32A can be protected here. When the terminal is fitted, a simultaneous electrically conducting contact is made between the mounting rail (earth) and the reference potential (ground) of the protection circuit in the terminal. Optical identification of the terminal based on the type of protected switching and the voltage level. The terminal can be labelled or marked.  
Short specification
Feed-through terminal with a varistor as central protection between the signal line connection and the mounting rail potential, TS 35 contact base. Version: 120 V UC
