What this MCCB brings to a panel
The Siemens SENTRON 3VA2325-5HN32-0HC0 is a 3-pole molded case circuit breaker rated for 250 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed as the panel warms up. The factory-fitted shunt trip (STL) and two auxiliary switches HQ give you remote tripping capability and status feedback without adding accessories later.
At 240 V it clears 187 kA, which is high enough for most service-entrance and large feeder applications. At 415 V the rating drops to 121 kA, still substantial for industrial distribution. These are the values you'd use for selective coordination studies with upstream and downstream devices.
Built-in trip and signaling
Two auxiliary switches HQ report open/closed status back to the control system. No undervoltage release is fitted, so if you need UVR for machine safety, that's a separate add-on.
Dimensions are 248 mm high, 138 mm wide, 110 mm deep — a standard SENTRON 3VA frame size for 250 A.
