Three poles, line protection design. The interrupting ratings are the headline: 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V. That 330 kA at 240 V puts it in the high-fault-current class for industrial distribution, not a light commercial panel. Trip indicator and voltage trigger present; undervoltage release is not fitted.
That 86 mm depth matters for shallow enclosures — verify gland plate clearance before cutting the back panel.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
330 kA at 240 V AC, which is a high-fault-current rating suitable for industrial main feeders or large sub-distribution boards.
It includes a shunt trip (STL) for remote opening. Undervoltage release is not fitted on this variant.
Standard Siemens SENTRON documentation includes RoHS and REACH declarations; UL and IEC certifications are typical for the 3VA series. Specific certificates can be provided with the RFQ.
