SENTRON 3VA2 MCCB — 25 A, 4-Pole, ETU320
The ETU320 trip unit supports an adjustable current range from 38 A minimum to 300 A maximum, giving the specifying engineer flexibility to match the breaker to the actual load without swapping hardware. At the 25 A continuous rating, the breaker is set at the lower end of that range, suitable for smaller feeder circuits or sub-distribution boards. Breaking capacity is substantial: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V.
Dimensions are 181 mm height, 140 mm width, and 86 mm depth.
The paperwork — RoHS, REACH, CE, and UL/IEC compliance declarations — is standard with the shipment; Siemens provides these on request for each production batch.
