Product details

The headline number here isn't the 25 A — it's the interrupting capacity. This breaker clears 330 kA at 240 V, 242 kA at 415/440 V, and still holds 187 kA at 500 V. The adjustable overload trip range spans 38 A minimum to 300 A maximum, with a 15 A initial value and full-scale set at 25 A. No need to uprate for a hot panel top. Power loss is negligible at 0.5 W max — won't heat up a sealed enclosure.

Panel fit — footprint and integration

Dimensions: 86 mm deep, 105 mm wide, 181 mm tall — or 3.39 × 4.13 × 7.13 inches.

The closest functional peer is 3VA2025-8HM42-0AA0. Both are 3-pole, 25 A SENTRON MCCBs with the same line-protection design. The -7HM32 lacks a trip indicator and undervoltage release that the -8HM42 may include.

Frequently asked questions

What is the closest functional second-source to 3VA2025-7HM32-0AA0?

The 3VA2025-8HM42-0AA0 is the closest peer — same 3-pole, 25 A SENTRON MCCB, same footprint. The -7HM32 lacks a trip indicator and undervoltage release that the -8HM42 may carry; verify trip curve and accessory needs before substituting.

What is the depth of 3VA2025-7HM32-0AA0?

86 mm (3.39 in).

What is the width of 3VA2025-7HM32-0AA0?

105 mm (4.13 in).

Will 3VA2025-7HM32-0AA0 drop into a panel specified for 3VA2025-8HM42-0AA0 without rewiring?

Yes — same 105 mm width, 86 mm depth, and 181 mm height (–), so the mechanical fit and bus connections are identical. No rewiring needed for the footprint. However, verify the trip characteristics and accessory configuration match the original design, as the -7HM32 lacks a trip indicator and undervoltage release.
