1sna150025r2600 – sfr4
TE Connectivity SFR4 1SNA150025R2600 is a compact ENTRELEC 4 mm² spring clamp rated at 32 A with flexible conductor capacity from 0.2 to 4 mm² for compatible industrial terminal block assemblies.
Why Choose the TE Connectivity SFR4 1SNA150025R2600 Spring Clamp?
The TE Connectivity SFR4 1SNA150025R2600 is an ENTRELEC spring clamp component designed for reliable conductor termination within compatible industrial terminal block assemblies. The SFR4 combines a compact, rugged construction with spring connection technology, providing consistent conductor retention for control panels, automation systems and industrial electrical equipment.
Designed for conductors up to 4 mm², the SFR4 supports flexible conductors from 0.2 to 4 mm² and UL/CSA rigid conductor sizes from 24 to 10 AWG. The spring connection is rated at 32 A for the main circuit and has a short-time withstand current of 480 A for 1 s.
The SFR4 is designed for compatible terminal assemblies mounted on G32 (32 × 15 mm) DIN rail in accordance with IEC 60715. A recommended stripping length of 13 mm and 3.5 mm operating tool specification support efficient installation, while its extremely compact 0.6 g construction makes it well suited to high-density industrial terminal systems.
