Its TM-D trip unit provides thermal-magnetic overload and short-circuit protection (L and I curves) rated at 160 A at 40 °C. At 220/240 V AC the Icu rises to 40 kA; at 440 V AC it drops to 20 kA, and at 500 V AC to 15 kA, all per IEC 60947-2. The 3-pole configuration (3P) with three protected poles (3D) suits three-phase distribution. The front-facing connections (upside and downside) make for straightforward bus-bar or cable routing. IP40 protection keeps out tools and debris but not moisture — mount inside a panel with a door.
Durability and thermal management
Mechanical durability is rated at 40,000 cycles; electrical durability varies with load: 40,000 cycles at 440 V at half-rated current (In/2), 20,000 cycles at full 440 V In, and 7,500 cycles at 690 V In. The 13.95 W power dissipation per pole (total ~42 W for three poles) means you need to account for heat rise in a sealed enclosure — derate the breaker if ambient exceeds 40 °C or if it's packed tightly with other heat sources.
It carries a suitability-for-isolation marking per that standard. The IK07 impact rating (IEC 62262) means it withstands a 2 J impact — enough for accidental tool drops during panel work. Operating altitude is 0–2000 m without derating, and up to 5000 m with derating. Relative humidity range is 0–95%.
