It is designed as a load-break disconnect without integral overload or short-circuit protection — meaning it isolates a circuit under load but relies on upstream protection devices for fault clearing. The main circuit connects via busbar connection at the front terminals. Dimensions: 105 mm wide, 158 mm high, 70 mm deep. The 70 mm depth leaves clearance behind the panel for busbar runs and auxiliary wiring. The latching endurance of 15 000 operations covers the mechanical life — this is a switch disconnector, not a daily-duty contactor, so it is sized for infrequent isolation, not continuous cycling. ## Auxiliary and options Four auxiliary switches (HQ type) are built in — two NO + two NC or four changeover, depending on wiring. The product extension for an optional motor drive is available (field-fit), so remote motorized operation can be added later without replacing the switch.","metaTitle":"Siemens 3VA1225-1AA32-0AE0 SENTRON Switch Disconnector, 250","metaDescription":"Siemens 3VA1225-1AA32-0AE0 SENTRON switch disconnector, 250 A rated continuous current, 3-pole, 4 HQ auxiliary switches, busbar connection.
