Product details

The Siemens SENTRON 3VA2025-5KP32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated 25 A continuous at 40 °C through 70 °C — no derating needed across the full panel ambient range, which simplifies BOM coordination in a warm enclosure. The interrupting capacity tells the story: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. Front face carries IP40 protection. Communication function is built in.

The 3-pole form factor with adjustable N-conductor protection (OFF, 40 % to 160 %) means it can serve as a main or feeder breaker in a 3-phase 4-wire panel where the neutral needs protection coordination. The IP40 front is adequate for a deadfront enclosure; keep it behind a sealed door if the panel sees dust or dripping water.

Frequently asked questions

Will 3VA2025-5KP32-0AA0 drop into a panel specified around 3VA2025-8HN42-0AA0 without rewiring?

Yes, the physical dimensions are identical — 105 mm width, 181 mm height, 86 mm depth — and both use the same 3-pole mounting pattern and busbar connections. The only difference is the communication wiring: if the panel was wired for the -8HN42-0AA0 without comms, you'll need to add the communication cable to use that function on the -5KP32-0AA0.
