TE Connectivity 1SNA146207R0200 DR2,5/5,2L,Ex is a compact 2.5 mm² spring-clamp feed-through terminal block rated at 24 A and 275 V for industrial control and automation wiring.
£0.96
The TE Connectivity 1SNA146207R0200, also identified as DR2,5/5,2L,Ex, is a compact spring-clamp feed-through terminal block from the Entrelec SNA miniblock range, designed for dependable conductor termination in industrial control, automation and electrical panel applications. Its compact construction is particularly suited to installations where DIN rail space is limited.
This terminal block has a 2.5 mm² rated cross-section and uses spring-clamp connections to provide secure, maintenance-friendly conductor termination without conventional screw tightening. The single-level design provides two clamping positions, while the light-grey polyamide insulating body offers industrial durability and a UL 94 V-0 flammability classification.
With a rated current of 24 A, rated voltage of 275 V and only 5 mm spacing, the DR2,5/5,2L,Ex provides a compact solution for high-density terminal arrangements. It mounts on a TH15-5.5 DIN rail in accordance with IEC 60715 and operates across a wide temperature range of -55 to +110 °C.
Spring-clamp terminal technology maintains conductor contact through continuous spring pressure, helping provide a secure electrical connection without the periodic retightening associated with conventional screw terminals. This makes the DR2,5/5,2L,Ex well suited to control-panel and machine-building applications where fast assembly and reliable long-term connectivity are important.
The compact miniblock format enables multiple circuits to be arranged efficiently on 15 mm DIN rail. Combined with its wide operating temperature range, V-0 polyamide insulation and small 5 mm width, the terminal is suitable for densely populated industrial control and automation assemblies.
