JST 2.5 TWIN Rail Mount Terminal Blocks Spring Type When components feel strong vibrations – in the rail industry, in wind power plants or in mechanical engineering – this requires maximum contact reliability. The spring-cage connection gives you a stable connection: the spring-cage always exerts the same force on the conductor, It's not influenced by the user. The ST Spring-cage connection terminal blocks have been developed for universal spring-loaded conductor contacting. The high contact force guarantees a vibration-proof, gas-tight connection with long-term stability. The compact front connection security easy operation. Spring-cage connection terminal blocks offer a large insertion space, which means that conductors with a nominal cross section can be wired both with and without ferrules. 3 ways , one push in two push out, without bridge fixed Due to the same accessories to have a low logistics costs You can open the terminal point wi…
