Product details

Breaking Capacity and Thermal Performance

The 3VA2025-8KQ36-0AA0: Breaking capacity is voltage-dependent: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. That covers most LV fault levels in North American and European 400/480 V panels.

The unit includes a communication function and ground-fault monitoring via summation current formation on the L-conductor, so it can feed status back to a BMS or PLC without an add-on module. No undervoltage release or trip indicator on this variant; those are separate order-code options.

Lifecycle status is current — this is an active catalog number from Siemens SENTRON.
