Its interrupting capacity hits 220 kA at 240 V, 154 kA at 415 V, and 75.6 kA at 440 V — numbers that matter when coordinating downstream faults on a high-fault panel feed.
Thermal-magnetic curve and temperature derating
The overcurrent release is a TM240 — thermal-magnetic, fixed, 240 A frame, set at the factory to the 160 A rating. The breaker holds 160 A flat from 40 °C through 50 °C, then derates to 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C.
Auxiliaries and trip options
The integrated auxiliary trip order code is 3VA9688-0BL30 if you need a spare or replacement.
Mounting and environment
Mechanical endurance rated at 15 000 cycles.
