At 63 A, this breaker handles a 15 kW resistive load at 240 V single-phase, or protects a subfeed in a distribution board. IP20 with connected conductors means the busbar stabs and terminals are finger-safe once wired, but the breaker itself isn't sealed against dust or moisture — it belongs inside an enclosure, not on a washdown line.
Overvoltage category 3 and energy limiting class 3 confirm it's rated for fixed-installation distribution panels, not just final circuits.
Solid conductors from 0.75 mm² to 25 mm², and stranded conductors from 0.75 mm² to 25 mm². That range covers control wiring up to main feeder tails in a single terminal.
Yes, the 5SJ6163-7 shares the same 1-pole form factor, 70 mm depth, single width unit, and DIN-rail mounting as the 5SJ3140-7. The key difference is the current rating — 63 A vs 40 A — so as long as the busbar and feeder are sized for 63 A, it's a direct mechanical swap.
