Its thermal-magnetic trip unit combines a bimetallic overload element adjustable from 9 to 14 A with a fixed magnetic trip set at 280 A, so it handles both sustained overloads and short-circuit faults in one package. Rated for uninterrupted duty per IEC 60947-4-1, it carries a 14 A continuous current and is listed for motor protection at 2.2 kW on 230 V AC up to 11 kW on 690 V AC. For transformer protection, the same unit covers 4 kW at 230/240 V AC up to 12.5 kW at 690 V AC. The breaking capacity (Icu) per IEC 60947-2 is 100 kA at 230 V AC, dropping to 15 kA at 400/415 V, 8 kA at 440 V, 6 kA at 500 V, and 3 kA at 690 V.
The 45 mm width (one standard modular unit) slots into a crowded enclosure without stealing extra space. Horizontal or vertical orientation is permitted. Power connections are spring terminals accepting 1 to 6 mm² solid or 1.5 to 4 mm² flexible wire (with or without ferrules). No screwdriver torque check needed — the spring cage holds the conductor firmly and resists vibration loosening. IP20 finger-safe protection on the front face; IK04 impact resistance. The enclosure is self-extinguishing at 960 °C per IEC 60695-2-11.
No substitution guesswork needed — this is the active, current-build part.
Altitude limited to 2000 m without derating. Climatic withstand conforms to IACS for marine and humid environments. Rated for 100,000 mechanical cycles and 100,000 electrical cycles under AC-3 duty at 415 V. Shock tested to 30 Gn for 11 ms, vibration to 5 Gn across 5–150 Hz — suitable for installation on machinery subject to moderate impact or continuous vibration. Power dissipation is 2.5 W per pole, so total heat load in the enclosure is 7.5 W at rated current.
