1sna295393r2200 – hd4/9.ff4.v0

Why Choose the TE Connectivity 1SNA295393R2200 HD4/9.FF4 V0 Stud Terminal Block?

The TE Connectivity 1SNA295393R2200, also identified as HD4/9.FF4, is a 4 mm² feed-through stud terminal block designed for secure industrial conductor termination. Unlike the single-stud HD4/9.F4.2 configuration, the HD4/9.FF4 incorporates two M4 stud terminals, providing a robust stud-to-stud feed-through connection for conductors fitted with suitable tubular cable lugs.

The terminal is rated at 32 A and 500 V AC/DC under NFC specifications and accommodates tubular-lug conductor sizes from 1.5 to 4 mm². Each connection uses an M4 × 11.5 mm stud equipped with a self-locking nut, spring washer and washer, helping create secure mechanical and electrical connections in demanding industrial environments.

Its beige UL 94V-0 polyamide housing, DIN-rail mounting and compact format make the HD4/9.FF4 suitable for machinery, control panels, transportation equipment and industrial distribution systems. The terminal operates across a broad temperature range of -55 to +110 °C and supports TH35 as well as reinforced Type 2 rail mounting.
