Product details

Siemens 3VA1225-6EF32-0AF0 — SENTRON MCCB, 250 A, 3-Pole

This rating holds at 45 °C and 50 °C as well, then derates to 243 A at 55 °C and 230 A at 65 °C — the thermal curve matters if your panel runs hot (–). The TM240 thermal-magnetic release provides fixed overload and short-circuit protection, with a trip indicator for quick fault identification on the panel face. Breaking capacity reaches 220 kA at 240 V, 154 kA at 415 V, and still 30 kA at 500 V — sufficient for high-fault utility feeds or transformer secondaries where upstream coordination demands a high-interrupting device (–).

Panel Integration & Physical Fit

The auxiliary switch configuration is 1 auxiliary switch + 1 trip alarm switch HQ, wired for status feedback and remote trip indication. No undervoltage release or ground-fault module is fitted.
