What this 5SJ4 MCB delivers for the panel line
The 5SJ4314-7HG42: The C-curve characteristic (tripping between 5 and 10 times rated current) suits general-purpose distribution and moderate inrush loads like contactor coils and small transformers. The part is halogen-free, silicon-free, and sealable — important for harsh or clean-room environments where outgassing or particulate contamination must be avoided.
Mounting and terminal detail
Width is 54 mm (3 modular units) and depth 70 mm, fitting standard DIN-rail enclosures without protruding beyond the front panel. The combined terminals top and bottom accept copper conductors; torque to 3.5 Nm for 60/75 °C rated wires. No tunnel terminals — use ring or fork lugs. Mount in any orientation on standard rail (fastening method: on standard mounting rail). Rated for ambient temperature from -40 to 75 °C and vibration up to 50 m/s², so it handles outdoor cubicles, machine-mounted panels, and rooftop installations.
