Breaking capacity — what the ratings actually mean for your panel
The fuse backup ratings tell you what gL/gG fuse to coordinate with: 32 A at 400 V and 500 V, dropping to 25 A at 690 V — this is the maximum fuse rating that preserves selectivity and lets the breaker clear faults within its own withstand.
Clearance and integration into a panel
That 50 mm vertical gap is the one that catches people — if you stack breakers without that headroom, arc flash gases can't vent properly and the device may not clear a fault. Terminals accept 2x 0.75–2.5 mm² solid or stranded, or 2x 4 mm² — sized for the typical motor-circuit conductor. M3 screw terminals on the main contacts. Operating temperature range -20 to +60 °C, storage/transport -50 to +80 °C — fine for most indoor panel environments; if the panel sits in a non-conditioned warehouse in a hot climate, check the 60 °C ceiling against the internal temperature rise.
