It carries phase failure detection as standard, which is essential for preventing single-phasing damage on three-phase motor loads.
That simplifies panel thermal calculations: you don't have to upsize the frame for a warm enclosure. The interrupting capacity drops to 75.6 kA at 500 V and 4.5 kA at 690 V, so verify the available fault current at your system voltage before specifying. Maximum power loss is 19.7 W, which is moderate for a 160 A frame. That matters for enclosure heat rise — account for it in the thermal budget if the breaker is in a sealed, non-ventilated panel alongside other heat sources.
The breaker accepts up to 4 HQ auxiliary switches, configurable for status signaling or remote trip indication. No undervoltage release or shunt trip is fitted from the factory; those are ordered separately if needed. The basic switch variant is 3VA2216-5MN32-0AA0 — the -0AE0 suffix indicates the factory-fitted accessories and packaging variant. If you're replacing an existing unit, verify the accessory configuration matches your current installation.
