The front terminal accepts busbar connections, and the unit carries an undervoltage release (UVR) coil rated 120–127 V AC 50/60 Hz, plus 2 auxiliary switches and 1 trip alarm switch, all HQ type. The 250 A rated continuous current (Iu) governs the load it can carry without overheating — sized for a feeder or large motor branch circuit where the disconnect only needs to make and break under load, not clear faults. The 3-pole configuration handles three-phase AC circuits up to 690 V AC (max rated operational voltage) or DC circuits up to 500 V DC. HQ denotes high-qualified contacts rated for low-level switching. The mechanical endurance of 15 000 cycles is typical for a disconnect of this frame size — expect it to outlast the panel's service life in normal switching duty. The unit measures 70 mm deep by 105 mm wide by 158 mm tall — fits a standard MCCB cutout in a panel or enclosure. The UVR coil draws from a 120–127 V AC control transformer; verify the control circuit can supply the coil inrush without dropping below the dropout threshold. The auxiliary and alarm switches are wired separately for status feedback.","metaTitle":"Siemens 3VA1225-1AA32-0CH0 SENTRON Switch Disconnector, 250","metaDescription":"Siemens 3VA1225-1AA32-0CH0 SENTRON switch disconnector, 250 A rated continuous current, 3-pole, IP40 front, undervoltage release.
