It's built for industrial panel protection — overcurrent and short-circuit isolation on lighting, control transformers, and general distribution circuits where the inrush isn't brutal but still needs a delayed trip compared to a B-curve. Rated operational voltage maxes out at 440 V AC for both single-phase and multi-phase operation, with an overvoltage category III rating — meaning it's designed for fixed-installation distribution boards, not for outlet-level protection.
At 40 °C it's 9.4 A, at 50 °C it's 8.7 A, and at 60 °C it drops to 8.1 A.
Mounting position is any, which helps in tight retrofit panels.
