TE Connectivity offers an extensive range of connection technologies for transportation following the acquisition of ABB’s ENTRELEC terminal block business. From the supply and distribution of power to the connection and protection of signals, the ENTRELEC terminal blocks can meet all the harsh railway and marine requirements, such as vibration and shock (IEC61373), temperature variations and corrosive atmospheres (IEC60068), smoke toxicity (EN45545, HL3-R22, NFPA130) and marine-related certifications (BV Marine, DNV, RINA, RMRS).
For the rolling stock application, the pull-out proof HD stud product line is used in train coaches and subways with a service history of near 40 years. For controlling signaling and safety lines, the Fast-on, ADO System and SNK PI-Spring terminal blocks provide flexibility, high connection density, and screw-less technology. For passenger and merchant ships and cargos, the D-type power blocks and the SNK Screw / PI-Spring terminal blocks have all passed the damp heat, dry heat and cold tests performed by Bureau Veritas for IEC60068. The SNK product line is also compliant with the DNV, RINA and RMRS certifications.
The SNK PI-Spring product line is the last generation of push-in/spring terminal blocks which can be both installed on trains and boats. It is also suitable for offshore oil and gas infrastructures, as it is certified IEC Ex, ATEX, UL hazardous locations (hazloc), EAC Ex and BR‑Ex. For more info, visit TE Connectivity.
