The TE Connectivity / Entrelec DB2.5/10.4L 1SNA290251R1200 is a compact grey spring-clamp feed-through terminal block from the SNA Spring range, designed for reliable conductor connections in industrial control panels, automation systems and electrical distribution assemblies. Its compact Miniblock format provides multiple connection points while conserving valuable panel space.
The DB2.5/10.4L features four spring-clamp connection positions on a single level. Spring connection technology maintains controlled contact pressure without relying on installer-applied screw torque, while front-entry wiring makes conductors readily accessible during panel assembly, testing and maintenance.
Rated at 24 A and 800 V, the 1SNA290251R1200 accepts flexible conductors from 0.12–2.5 mm² and rigid conductors from 0.12–4 mm². Its compact 10 mm width, direct mounting arrangement and robust polyamide insulation make it a practical choice for high-density industrial wiring installations.
Spring-clamp terminal technology applies mechanically controlled pressure to the conductor, providing repeatable electrical contact without depending on installer-applied screw torque. The spring mechanism also compensates for conductor settling, helping maintain dependable connections in industrial electrical installations over extended service periods.
The DB2.5/10.4L combines this connection technology with four connection positions and a compact 10 mm-wide Miniblock format. Front-entry wiring improves accessibility, making the terminal particularly useful for space-conscious control panels and automation equipment where efficient installation and reliable conductor distribution are required.
