Spring and push-in DIN-rail terminals

Spring and push-in terminals maintain contact pressure through a spring element. SELOS WTPN accepts solid conductors and suitably ferruled flexible conductors by direct insertion; the opening button is used for other accepted wire types. The family includes feed-through, protective, multi-level and functional blocks, allowing a consistent assembly method across different panel functions.

Selection considers conductor type and size, required levels and access direction. Jumper channels and marking elements help group potentials while leaving test points and conductor-release mechanisms accessible.
