The Siemens SENTRON 3VA2225-5HL42-0DA0 is a 4-pole molded case circuit breaker rated for 250 A continuous current at 40 °C — that's the full-load ampacity it holds without derating up to 50 °C. The interrupting rating at 415 V is 121 kA, and at 690 V it's 4.5 kA — the SCCR you need depends on your system voltage and available fault current.
Interrupting capacity — matching to your available fault current
The interrupting ratings span the voltage range: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. That 121 kA at 415 V is the figure that matters for most European industrial panels fed from a 400 V transformer — it puts this breaker well above the typical 50–65 kA SCCR requirement, giving you selectivity headroom downstream.
Dimensions: 181 mm height, 140 mm width, 86 mm depth. The breaker mounts directly to a mounting plate or DIN rail via the SENTRON quick-latch system; no tools needed for the rail snap-on. The 4-pole width at 140 mm is wider than a 3-pole equivalent, so account for that in your panel layout.
Undervoltage release and auxiliary options
No auxiliary switch is fitted from the factory, so if you need a contact position indication for the PLC or a status feedback for the panel HMI, you'll add a separate auxiliary switch block. The UVR itself is the standard 3VA2 accessory — it trips the breaker when the control voltage falls below 70–35% of rated voltage, per IEC 60947-2. Maximum power loss is 50.5 W at rated current, which matters for thermal management in a sealed enclosure.
