It breaks fault currents up to 10 kA at 400 V AC, certified to both EN 60898 and IEC 60947-2 — the dual rating means it qualifies for residential/infrastructure panels (EN 60898) and industrial control circuits (IEC 60947-2) without a separate spec review.
C-curve trips between 5× and 10× rated current (5–10 A for this 1 A unit), so it handles moderate inrush from small motor starters, contactor coils, or lighting ballasts without nuisance tripping. Two-pole switching (2P) means both line and neutral are disconnected on fault or manual isolation — required for single-phase final subcircuits in many national wiring rules. Frequency range is 50/60 Hz, so it works on either mains standard without derating.
Sealable (can be locked in OFF position with a padlock) for lockout/tagout compliance.
