The 3-pole design suits three-phase feeder or motor branch circuits in switchboards, panelboards, or standalone enclosures. ## Thermal derating and temperature range Above that, it derates: 245 A at 55 °C, 239 A at 60 °C, 234 A at 65 °C, and 228 A at 70 °C. The 138 mm width is the critical panel cutout dimension — verify the mounting footprint against your existing switchboard or enclosure backplate before ordering. The 110 mm depth includes the case body; allow additional clearance for rear terminals and arc-chamber venting per the manufacturer's installation guide.","metaTitle":"Siemens 3VA1325-7MH32-0AA0 SENTRON MCCB, 250 A, 3-Pole","metaDescription":"Siemens 3VA1325-7MH32-0AA0 SENTRON molded case circuit breaker, 250 A continuous, 3-pole, 440 kA at 240 V.
