Applications & Use Cases

The 3VA1225-4EF32-0AA0 is configured for busbar-mounted installation in low-voltage switchgear panels and distribution boards. Its 36 kA breaking capacity at 415 V covers high fault-current environments typical of transformer secondaries up to ~630 kVA at standard impedance. The adjustable thermal-magnetic trip unit lets engineers dial in overload protection from 175 A to 250 A without changing the frame, reducing panel redesign time when load profiles shift. Three-pole construction handles three-phase distribution without a neutral pole, appropriate where neutral is bonded at the transformer.
