It's rated 20 A at 30 °C ambient, and its breaking capacity is 10 kA under both EN 60898 and IEC 60947-2 — that means it can safely interrupt fault currents up to 10,000 A without welding or exploding, which is the standard for most residential and light-commercial distribution boards. At 40 °C the continuous rating derates to 18.48 A, at 45 °C to 17.6 A, and at 55 °C to 15.92 A, so if the panel runs hot, size up accordingly. This is a 1-module-width (18 mm) unit, 90 mm tall, 76 mm deep (70 mm installation depth), so it fits standard DIN-rail enclosures without crowding adjacent poles. Rated for AC only, single-phase up to 250 V or multi-phase up to 440 V.
Panel integration and compliance notes
Sealable (can be locked in the OFF position for lockout/tagout). Halogen-free and silicon-free — important for clean-room or sensitive-environment panels where outgassing can contaminate contacts or optics. Touch protection is built in, so no additional finger-safe shrouds needed on the line side. Energy limitation class 3, which means it limits let-through energy well — good for downstream component protection.
