What this 5SJ4 MCB delivers for the panel line
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. 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.
