The TE Connectivity D4/8.D2.P.SFD 1SNA400272R1600 is a specialised two-level screw-clamp fuse terminal block from the ENTRELEC SNA range, designed for protected signal and control circuits in industrial electrical installations. It combines fused circuit functionality, multiple connection positions and DIN rail mounting in a compact 8 mm-wide terminal format.
The D4/8.D2.P.SFD provides 6 positions across 3 circuits and incorporates a lever disconnect mechanism. Its screw-terminal connections accept conductors up to a nominal 4 mm² / 12 AWG, with flexible conductor capacity from 0.5–4 mm² and rigid stranded conductor capacity from 0.5–6 mm².
Rated at 6.3 A and 300 V IEC, with the same 6.3 A / 300 V ratings under UL and CSA specifications, the terminal is suited to fused signal circuits requiring reliable protection and convenient servicing. Its grey Polyamide 6.6 housing provides IP20 protection and a UL94 V-0 flammability rating for professional industrial panel applications.
The D4/8.D2.P.SFD combines terminal connection, fuse functionality and circuit disconnection within one compact DIN rail component. Its two-level, three-circuit architecture helps panel designers achieve greater wiring functionality without unnecessarily increasing terminal-strip width, making it particularly useful where enclosure space is limited.
Screw-clamp termination provides a familiar and serviceable connection method, while the 0.5 N·m tightening torque and 9.5 mm stripping length support consistent conductor installation. The integrated lever disconnect arrangement also allows circuits to be isolated conveniently during commissioning, testing and maintenance.
