The Siemens 3VA1332-6EE32-0AA0 is a SENTRON 3-pole molded case circuit breaker (MCCB) rated for continuous current Iu of 320 A at 40 °C, with no derating required up to 50 °C per the datasheet. Breaking capacity reaches 220 kA at 240 VAC, 154 kA at 415/440 VAC, and 121 kA at 500 VAC — figures that place this unit in the high-interrupting category for large industrial feeders and transformer secondaries. The unit is designed for line protection (non-communicating), with no ground-fault monitoring or communication function integrated.
Dimensions are 248 mm height, 138 mm width, 110 mm depth — a standard SENTRON 3VA1 frame size that fits existing 3VA panel cutouts and busbar arrangements. Front IP40 protection is suitable for enclosed switchboard installation; the unit accepts optional motor drive accessories for remote operation. Operating temperature range is -25 °C to 70 °C, with a derating curve above 55 °C (313 A at 55 °C, 306 A at 60 °C, 299 A at 65 °C, 292 A at 70 °C).
The lifecycle stage is recorded as current production — this is an active catalog item in the SENTRON 3VA series, not subject to phase-out or last-time-buy as of the latest manufacturer data.
