The interrupting capacity tells the real story: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. At 415 V, the 121 kA rating still covers most heavy industrial switchboards. Current derating is published across the operating temperature range: full 160 A up to 50 °C, then a gentle roll-off 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.
Sourcing and lifecycle — still in active production
The breaker ships with a factory-fitted shunt trip (STL) release, order code 3VA9688-0BL32, for remote tripping.
Footprint is 76.2 mm wide (3-pole), 130 mm tall, and 70 mm deep — a compact three-module width for a 160 A frame. If your application requires those extras, you would step up to a 3VA1 with the electronic release (ETU) or add external modules.
