Product details

That means you can dial in the trip settings to match the downstream load without swapping the breaker body — useful when the same panel frame gets wired for different motor or feeder currents. Interrupting capacity is the headline number here: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V.

Panel fit and wiring constraints

The case dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON 3VA2 panel-mounting kits without re-drilling the gland plate. The IP40 front protection is typical for a switchboard interior; keep it behind a locked door or a cover plate. If the BOM calls for a motor drive accessory, this base unit accepts the optional motor drive add-on (Product Extension / Optional / Motor Drive: Yes).

For BOM-freeze or compliance documentation, the brand standard for this series includes RoHS, REACH, and IEC/UL certifications as part of the SENTRON release package. Specific declaration files are available on request at quote time.

Frequently asked questions

Where can I buy the 3VA2025-5HM32-0AA0 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is published here.

What is the interrupting capacity of this MCCB at 415 V?

At 415 V the interrupting capacity is 121 kA, which covers high-fault-current installations like transformer secondaries without requiring upstream coordination.

Does the 3VA2025-5HM32-0AA0 drop into a panel designed for the 5SQ2370-2YA05?

The 3VA2025-5HM32-0AA0 is a SENTRON 3VA2 frame MCCB with a 105 mm width, 181 mm height, and 86 mm depth — a standard 3-pole MCCB footprint. The 5SQ2370-2YA series are different form-factor devices; verify mounting hole pattern and bus-bar spacing before assuming direct swap without rewiring.

What compliance documentation is available for this part?

Standard SENTRON documentation package includes RoHS, REACH, and IEC/UL certification declarations. Specific compliance certificates are provided at quote time upon request.
