Its breaking capacity reaches 242 kA at 240 V AC and 187 kA at 415 V AC, dropping to 9 kA at 690 V AC — the voltage-dependent curve means you size the SCCR for the actual line voltage, not the highest number. Max power loss is 63.5 W, which matters for thermal management inside a sealed panel.
The basic switch order code is 3VA2440-6HN32-0AA0. This suffix -0HH0 adds the shunt trip and auxiliary switch package.
It includes a shunt trip release (STL), 2 auxiliary switches, and 1 trip alarm switch (HQ). No undervoltage release or ground-fault monitoring.
