The adjustable trip range spans 600 A minimum to 4 800 A maximum, giving the commissioning engineer flexibility to set the instantaneous pickup to match cable or busway ampacity without swapping breaker frames. Interrupting capacity is what separates this MCCB from a standard thermal-magnetic: at 240 V it clears 330 kA, at 415 V and 440 V it clears 242 kA, at 500 V it clears 187 kA, and at 690 V it clears 9 kA.
Built-in auxiliary and undervoltage release
The auxiliary contacts report breaker position (open/closed) to a PLC or status lamp; the trip alarm switch signals a fault trip distinct from manual opening. The basic switch order code is 3VA2440-7HL32-0AA0, which is the raw breaker without auxiliaries; this -0DH0 suffix adds the aux switch block and UVR.
That 138 mm width (5.43 inches) is the standard 3-pole MCCB footprint for this SENTRON frame size; it occupies three adjacent 45 mm module positions on a DIN rail or mounts to a backplate with the factory-supplied screws. Maximum power loss is 66 W at rated current — account for that heat in the panel thermal budget if the breaker is enclosed without forced ventilation.
Environmental limits and storage
No ground-fault monitoring version is included (that would be a different suffix).
