It carries a rated continuous current Iu of 160 A and an interrupting capacity of 187 kA at 240 V AC, which drops to 121 kA at 415 V and 4.25 kA at 690 V. A shunt trip release (STL) is integrated for remote tripping via a control signal — useful for emergency-stop or supervisory shutdown circuits.
Panel integration and physical fit
Thermal derating and ambient limits
The 160 A rating holds up to 50 °C. Above that, derate linearly: 154 A at 55 °C, 148 A at 60 °C, 142 A at 65 °C, and 136 A at 70 °C. Maximum power loss is 25.5 W — account for that heat in a sealed enclosure.
