The interrupting capacity hits 187 kA at 240 V, dropping to 121 kA at 415 V and 75.6 kA at 440 V — enough to handle high-fault utility feeds or transformer secondaries without cascading upstream breakers.
Thermal derating and power dissipation
The breaker holds its 160 A rating from 40 °C through 50 °C, then derates to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. Maximum power loss is 40.5 W — factor that into your enclosure's thermal budget if you're stacking multiple breakers in a sealed panel.
Panel fit and mechanicals
The 70 mm depth leaves clearance for rear-access wiring and gland plates.
The breaker includes two HQ auxiliary switches (form C) and an undervoltage release (UVR).
The storage ceiling is higher than the operating ceiling — that's typical for shipping and warehouse conditions. No ground-fault monitoring version is included; if you need GF protection, you'd add an external module or choose a different variant.
