Panel Fit and Clearances
Required clearances: 50 mm above and below, 30 mm to the sides, and zero forward or backward. That 50 mm vertical gap is for heat dissipation from the bimetal trip element — don't cram it against a cable duct or another heat source. Terminals accept 2x (0.75 to 2.5 mm²) solid or stranded, or 2x 4 mm², with M3 screws for the main circuit. That's enough for the motor leads on a 3–5 kW motor at 400 V.
Protection Characteristics
Trip Class 10 means the thermal overload element trips within 10 seconds at 7.2× the current setting — fast enough for standard squirrel-cage motors, but not for high-inertia loads that need Class 20 or 30. Breaking capacity varies with voltage: 100 kA at 240 V and 400 V, 100 kA at 500 V, then drops to 10 kA at 690 V. The gL/gG fuse coordination values are 25 A at 400 V, 32 A at 500 V, and 25 A at 690 V — these are the maximum upstream fuse ratings that still allow selective coordination with the breaker's magnetic trip.
