The Siemens SENTRON 3VA2325-5MN32-0CL0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuously from 40 °C all the way up to 70 °C — no derating needed across that range. That UVR means if the control voltage drops, the breaker trips, which is exactly what you want on a motor circuit where a brownout could stall the load and cook the windings. The interrupting capacity is serious: 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V. That covers most industrial low-voltage distribution panels — if your fault current is within those numbers, this breaker clears it without welding its contacts shut.
No ground-fault monitoring module on this variant (that's the "Without" in the spec), so if you need GFCI, look at the 3VA2 family with the "-0BB0" suffix.
Environmental and thermal limits
Max power loss is 40 W — that's the heat it dumps into the enclosure, so factor that into your panel cooling if you're packing several breakers side by side.
What's on the basic switch and auxiliary release
The basic switch is order code 3VA2325-5MN32-0AA0 — that's the base MCCB without the auxiliary switches. The 0CL0 variant adds the 2 auxiliary switches, trip alarm, electrical alarm, and undervoltage release. If you're retrofitting a panel that already has a basic switch, you can order the add-on kit separately.
