1sna167281r2100 – pe 257
TE Connectivity 1SNA167281R2100 PE 257 is an Entrelec SNA terminal block marking accessory designed for clear identification of compatible industrial terminal block assemblies.
Why Choose the TE Connectivity 1SNA167281R2100 PE 257 Terminal Block Marker?
The TE Connectivity 1SNA167281R2100, also identified as PE 257, is a specialised terminal block marking accessory from the TE Connectivity / Entrelec SNA range. Designed for identification within compatible terminal block assemblies, it provides a practical way to organise and identify electrical connections in control panels, switchgear and industrial automation equipment.
The PE 257 is classified specifically as labelling for terminal blocks, making it an identification component rather than an electrically conductive terminal accessory. Clear terminal marking supports efficient installation, inspection, commissioning and fault finding by helping technicians associate individual connection points with the appropriate circuit or wiring information.
With an approximate net weight of just 1.2 g, the 1SNA167281R2100 is a lightweight component designed for compatible Entrelec terminal block systems. It is supplied in manufacturer packs of 10 and is identified by EAN 3472591672817.
