DT Direct Terminals - direct plug-in connection terminal blocks
Phoenix Contact push-in terminal blocks DT have been developed for direct conductor connection. This means that solid conductors or conductors with ferrules can be directly inserted into the terminal block without tools.
The technical data of the DT terminal blocks clearly surpass the requirements of the relevant standards, as in the case of all other connection methods. 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-free 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 a lead-free, galvanic nickel or tin plating. The contact force for the direct push-in connection is applied by a leg spring of high-strength chromium-nickel spring steel.
This elastic plastic with high impact strength is halogen-free and UV-resistant. Further characteristics are the good tropical and termite resistance, high chemical resistance and the excellent aging characteristics.
Polyamide 6.6 can be used with operating temperatures up to 130°C and is certified for the inflammability class V0 in accordance with UL 94.
