Characteristic A trips between 2 and 3 times rated current — it's the fastest standard curve, meant for protecting semiconductor circuits or long cable runs where you need to clear a fault before the electronics cook. The 4-pole (3P+N) configuration switches all three phases plus the neutral, which is required in TN-S or TT systems where you need to isolate the neutral on a fault. Rated current derates with ambient temperature: 25 A at 35 °C, 24 A at 40 °C, 23.5 A at 45 °C, 22.98 A at 50 °C, 22.45 A at 55 °C, 21.9 A at 60 °C. If your panel runs hot, size the load accordingly — don't count on the full 25 A above 35 °C. Sealable for lockout/tagout compliance.
