The 1P+N configuration switches the line conductor and provides a switched neutral. The 2 width units occupy two modular slots on a standard DIN rail. The sealable feature allows lockout/tagout compliance.
Deployment context
Installation depth is 70 mm, which fits typical distribution board enclosures. Ambient temperature range is -20 to +45 °C, with periodic excursions to +55 °C at up to 95% humidity. That covers most indoor panel environments, but if your panel sits near a furnace or in direct sun, derate the 63 A per the manufacturer's thermal curve above 40 °C.
The 5SJ6563-7 carries a halogen-free and silicon-free construction, which matters for environments where outgassing can contaminate contacts or optics — think clean rooms or sealed enclosures. Vibration resistance is tested per IEC 60068-2-6 at 50 m/s² from 25 to 150 Hz and 60 m/s² from 10 to 150 Hz, so it holds up on machinery or in mobile installations. Mechanical service life is 20 000 switching cycles typical — adequate for normal branch-circuit duty; if you're cycling it daily for load shedding, consider a contactor instead.
