It is configured as an SD100 — a basic disconnect without integral overload or short-circuit protection elements. The unit ships with an undervoltage release (24 V DC) and two auxiliary changeover switches fitted. The 250 A continuous rating (In) sets the maximum uninterrupted load this disconnector can carry under normal service conditions. Because the SD100 variant omits overload and short-circuit protection, it functions purely as an isolating device — the upstream feeder breaker or motor circuit protector must provide the overcurrent protection. The 3-pole configuration suits three-phase line or load isolation in distribution panels, motor control centers, or switchgear assemblies. ## Integration notes The undervoltage release coil draws 24 V DC; verify the control transformer and wiring polarity before energizing.","metaTitle":"Siemens 3VA1225-1AA32-0BB0 SENTRON Switch Disconnector, 250A","metaDescription":"Siemens SENTRON 3VA1225-1AA32-0BB0 switch disconnector, 250A, 3-pole, IEC frame 250.
