The 3-pole configuration handles three-phase circuits up to 480 A maximum (frame rating) and 800 V insulation voltage.
Rated short-circuit breaking capacity is 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The steep drop at 690 V (3.7 kA) means this frame is not intended for 690 V distribution; it is optimized for 240–500 V systems where fault currents can be very high.
Approvals and documentation
The SENTRON 3VA series carries UL, CSA, and IEC certifications (specific marks per variant). The ETU550 trip unit supports communication protocols for integration with energy management systems. RoHS and REACH compliance documentation is available from Siemens — standard for this product family.
