Key ratings and what they mean for your panel
The 3VA2325-7HL32-0AA0: The 250 A continuous rating holds across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel sizing in warm enclosures. The 800 V rated insulation voltage (Ui) confirms the breaker can be applied in 480/277 V and 600 V systems with margin. The IP40 front protection means the breaker face is protected against tools and small wires (1 mm diameter and larger), but the body is not sealed against water ingress — standard for panel-mounted MCCBs where the enclosure provides the overall IP rating. Dimensions are 248 mm height, 138 mm width, 110 mm depth, fitting standard Siemens 3VA mounting patterns and busbar systems.
