The 25 A rating handles a 5.5 kW resistive load at 230 V or an 11 kW three-phase motor branch (derated for duty). If your panel's fault level exceeds that, step up to a 6 kA or 10 kA rated MCB — this one will not clear a fault above 3 kA without welding its contacts. Overvoltage category 3 and energy limiting class 3 are standard for distribution boards downstream of the main incoming supply. Energy limiting class 3 means it restricts let-through energy (I²t) enough to protect downstream wiring and devices within its rating — a coordination requirement for selective tripping.
