The Siemens 3VA2325-6HL32-0HC0 is a SENTRON molded case circuit breaker (MCCB) rated for 250 A continuous current across its full operating temperature range from -25 °C to 70 °C — no derating needed up to that 70 °C ceiling. This is a line-protection device, not a motor-protection breaker, so it's sized for feeder and distribution circuits in industrial panels. Three poles, breaking capacity that steps down from 242 kA at 240 V to 7.5 kA at 690 V, meaning you size it for the available fault current at the point of installation.
Breaking capacity and selectivity
At 240 V this MCCB interrupts 242 kA — that's utility-grade fault current, typical for a main service entrance or a high-capacity sub-distribution board. At 415 V and 440 V it still holds 187 kA, which covers most industrial transformer secondaries. The drop to 7.5 kA at 690 V is sharp; if your system runs 690 V with high fault current, this breaker needs upstream current-limiting protection or a higher-rated frame.
Integrated auxiliaries and shunt trip
Factory-fitted with a shunt trip (STL) release and two auxiliary switches (HQ design). The shunt trip lets you remotely open the breaker from a PLC safety output or E-stop circuit without running a separate undervoltage release coil. The two aux switches provide independent status feedback — one for the panel HMI, one for the remote SCADA input. No communication module on this variant; it's a straight hardwired device.
Panel fit and environment
Dimensions: 248 mm high, 138 mm wide, 110 mm deep. That 110 mm depth (4.33 in) is shallow enough for a 200 mm deep enclosure with room for gland plates and wiring gutters. The width at 138 mm (5.43 in) is standard for a 3-pole MCCB in this current class — it occupies one 6-inch-wide slot in a typical distribution panel. Storage range -40 °C to 80 °C; operating range -25 °C to 70 °C. Max power loss 37.5 W at full load — plan ventilation if you pack several in a sealed cabinet.
