Why Choose the TE Connectivity HD16/14.FF5.21.3 1SNA295012R1700 M5 Stud Terminal Block?

The TE Connectivity 1SNA295012R1700, manufacturer designation HD16/14.FF5.21.3, is a robust two-position M5 stud feed-through terminal block designed for secure power connections in industrial and railway electrical systems. Part of the established TE Connectivity ENTRELEC stud terminal block range, it combines dependable bolted conductor termination with DIN rail mounting for demanding power distribution and equipment wiring applications.

The HD16/14.FF5.21.3 incorporates two M5 × 19.5 mm stud terminals, each designed for secure lug-terminated conductor connections. The stud assemblies use a self-locking nut, spring washer and washer, providing strong mechanical retention and reliable electrical contact where resistance to vibration and connection loosening is important.

With an NFC conductor capacity of up to 16 mm², a maximum contact current rating of 71 A and an operating voltage rating of 600 V AC, the 1SNA295012R1700 is designed for substantial industrial power connections. Its 14 mm spacing, beige polyamide housing and compatibility with TH35 DIN rails make it particularly suitable for modular electrical assemblies in industrial machinery and railway applications.
