Why Choose the TE Connectivity MA2.5/5 Yellow Feed-Through Terminal Block?
The TE Connectivity MA2.5/5, manufacturer part number 1SNA105486R1200, is a compact yellow screw-clamp feed-through terminal block from the ENTRELEC SNA series. Designed for reliable signal and control wiring, it provides a secure method of connecting incoming and outgoing conductors within industrial control panels, automation systems and electrical equipment.
With a nominal conductor size of 2.5 mm² and a narrow 5 mm pitch, the MA2.5/5 supports high-density terminal arrangements while conserving valuable DIN rail space. Its proven screw-terminal connection technology provides secure conductor retention, while the yellow polyamide 6.6 housing enables clear visual identification within colour-coded wiring assemblies.
The terminal is rated at 24 A and 1000 V under IEC specifications and accepts flexible conductors from 0.22–2.5 mm² and rigid stranded conductors from 0.2–4 mm². Compatible with G32, TH35-7.5 and TH35-15 DIN rails, the MA2.5/5 is a versatile connection solution for industrial signal, automation and control circuits and is supplied in a pack quantity of 50 pieces.
