Basically it's an RCBO that handles overload, short circuit, and residual current all in one DIN-rail unit, and we ordered it because of that it covers the full range form 1A all the way up to 63A depending on what you need.

The 30mA residual current setting is standard and that's what most buyers go with for general protection, though you can get other values customized if your setup requires something different.

It's 230/400V AC at 50/60Hz and comes in 1, 2, 3, or 4 pole configurations, with breaking capacity at 4 or 6kA depending on the variant — we usually stock the 6kA version since it's tighter tolerance than most for commercail installs.

SG65LE-63 RCBO Circuit Breaker

Mechanicla life is rated at 10,000 operations and the housing is flame-retardant PA66 nylon, which holds up better than cheaper ABS alternatives in warmer environments (operating range is -25°C to +60°C).

One thing you might not think to ask: teh screw terminals are standard but they're not the largest, so if you're running heavy-gauge wire you'll want to check the terminal capacity first.

Also, it's not suited for outdoor panels without additonal enclosure protection since IP20 is basically just basic dust and finger protection, not water-resistant.
