Product details

Siemens 3VA2340-7HM32-0AA0 — 400 A SENTRON MCCB with adjustable trip

The Siemens 3VA2340-7HM32-0AA0 is a SENTRON 3VA2 molded case circuit breaker rated 400 A continuous at 40 °C, with an adjustable thermal-magnetic trip unit covering 600 A minimum to 4 000 A maximum (full-scale value 400 A, initial setting 80 A). This is a line-protection design (not motor-protection curve), 3-pole, with no undervoltage release, no voltage trip, and no communication function. The interrupting ratings scale with system voltage: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V. Continuous current holds at 400 A up to 50 °C ambient, then derates linearly: 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, 340 A at 70 °C. Maximum power loss is 96 W at full load.

The breaker measures 110 mm deep, 138 mm wide, 248 mm high.
