What this MCCB carries and where it fits
The Siemens SENTRON 3VA2325-6HN32-0BL0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to that ceiling. Breaking capacity hits 242 kA at 240 V, 187 kA at 415/440 V, 121 kA at 500 V, and 7.5 kA at 690 V, so it handles high-fault utility feeds and large motor branch circuits without cascading upstream. The 110 mm depth, 138 mm width, and 248 mm height fit standard SENTRON 3VA2 panel cutouts; the 3-pole form factor matches three-phase distribution.
Auxiliary and release complement
Factory-fitted with an undervoltage release (UVR) and a full auxiliary switch block: 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ type). That covers remote status indication and undervoltage protection in one package — no separate add-on modules needed for basic signaling. The UVR drops the breaker on loss of control voltage, which is standard for emergency-stop and safety isolation circuits.
