Why Choose the TE Connectivity 1SNA146207R0200 DR2,5/5,2L,Ex Spring Terminal Block?
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.
