Push-in connection terminal blocks
Phoenix Contact push-in connection terminal blocks have been developed for direct conductor connection. This means that solid conductors or conductors with ferrules can be directly plugged into the terminal block without tools.

The technical data of the Push-In Technology terminal blocks clearly surpass the requirements of the relevant standards, as in the case of all other connection methods from Phoenix Contact. The gas-tight conductor contacting also fulfills special criteria, such as the vibration test in acc. with the railway standard EN 50155.
Material properties
All metal parts of the push-in terminal blocks are made of corrosion-resistant materials. The current-carrying metals consist of high-grade copper alloys. Especially advantageous is the low temperature rise due to good electrical conductivity.
The surface is protected by lead-free, galvanic nickel or tin plating. The contact force for the push-in connection is applied by a leg spring made of high-strength chromium-nickel spring steel.
Further characteristics are the good tropical and termite resistance, high chemical resistance and the excellent aging characteristics. Polyamide 6.6 can be used at operating temperatures up to 130°C and is certified for the inflammability class V0 in accordance with UL 94.
