It is designed as a load-break isolating device — it makes, carries, and breaks currents under normal service conditions, including overload conditions specified by the operator, but it provides no automatic overload or short-circuit protection. The part carries a shunt trip release (STL) that operates on 12–30 V DC or 24 V AC 50/60 Hz, allowing remote emergency-off or controlled disconnection from a PLC or safety relay output. The maximum AC operational voltage is 690 V 50/60 Hz, covering 400 V and 480 V systems with headroom; the DC rating maxes at 500 V, suiting it for battery banks or DC bus isolation in drives. Short-circuit withstand is rated at 3 kA for both 0.5 s and 1 s intervals — this is not a high-fault device; it expects upstream current-limiting fuses or a circuit breaker to clear faults above that level. The IP40 front protection means it is dust-protected but not washdown-rated; install it inside a panel with a door, not in a wet environment. The 3VA1225-1AA32-0HA0 occupies a 105 mm wide by 158 mm high by 70 mm deep footprint — a standard 3-pole MCCB cutout in a panel or enclosure. Main circuit connection is via busbar connection on front terminals, which means it is designed to bolt directly onto a horizontal or vertical busbar system, not to accept lugged cables on the rear. The optional motor drive (product extension) allows remote motorized operation for automated disconnection sequences. No auxiliary contacts are fitted as standard; if status feedback is needed, a separate auxiliary contact block must be added. ## Comparison with a sibling: 3VA1010-2ED32-0JA0 The key difference: the 3VA1225-1AA32-0HA0 is a switch disconnector only — no overcurrent protection — while the 3VA1010-2ED32-0JA0 is a full circuit breaker. If your BOM calls for a disconnector with separate upstream protection, the 3VA1225-1AA32-0HA0 is the correct part; if you need integrated protection, the 3VA1010-2ED32-0JA0 is the alternative. The 3VA1225-1AA32-0HA0 also has a larger frame (250 A vs 100 A) and a wider width (105 mm vs 76.2 mm), so it will not drop into a panel cutout designed for the 100 A frame without modification.","metaTitle":"Siemens 3VA1225-1AA32-0HA0 SENTRON Switch Disconnector, 250","metaDescription":"Siemens SENTRON 3VA1225-1AA32-0HA0 switch disconnector, 250 A rated continuous current, 3-pole, shunt trip release.
