Siemens 3VA2025-7HL46-0AA0 — 25 A SENTRON MCCB with ETU320 Trip Unit
The Siemens 3VA2025-7HL46-0AA0 is a 4-pole SENTRON molded case circuit breaker (MCCB) rated for 25 A continuous current, fitted with an ETU320 electronic trip unit. Per the datasheet, the continuous current rating holds flat at 25 A across the full ambient temperature range from 40 °C to 70 °C — no derating required up to the maximum operating temperature of 70 °C. The insulation voltage is rated at 800 V. Breaking capacity is specified at multiple voltage levels: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V. This is a line-protection design (not motor-protection) with no undervoltage release, no voltage trigger, and no communication function. The front face carries IP40 protection.
Dimensions and Panel Fit
Physical envelope: 181 mm height, 140 mm width, 86 mm depth. The 4-pole width of 140 mm is standard for this frame size; verify the existing panel cutout and busbar spacing against these dimensions before committing the BOM line. No trip indicator is fitted on this variant.
