What this 3VA2 MCCB carries and where it fits
The Siemens SENTRON 3VA2325-6HL32-0BL0 is a 3-pole molded case circuit breaker rated for 250 A continuous current, with a line-protection design and an undervoltage release (UVR) fitted as standard. The interrupting capacity reaches 242 kA at 240 V AC, 187 kA at 415/440 V, and 121 kA at 500 V — numbers that tell you this breaker handles high-fault utility feeds or transformer secondaries without cascading upstream. Full thermal rating holds flat from 40 °C through 70 °C, so no derating curve to chase in a warm enclosure. The auxiliary switch complement is 2 auxiliary switches + 1 trip alarm switch + 1 electrical alarm switch HQ, giving you remote status and trip indication without adding a separate accessory block. The basic switch supplied is 3VA2325-6HL32-0AA0, so the 0BL0 suffix adds the UVR and the full auxiliary set — a configured variant, not a bare frame.
Panel footprint and thermal budget
At 248 mm high × 138 mm wide × 110 mm deep, this breaker fits a standard MCCB cutout in a distribution panel or motor control centre. The 138 mm width is three-pole wide — verify your busbar centres and phase-to-phase clearance before laying out the gland plate. Maximum power loss is 40 W, which matters for internal temperature rise in a sealed enclosure; if you are packing multiple breakers in a row, sum the losses against your ventilation or cooling capacity.
