Product details

Interrupting capacity — the real headroom

The interrupting capacity tells you where this breaker can be installed without cascading upstream: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 7.5 kA at both 500 V and 690 V.

Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a compact 3-pole MCCB footprint that fits standard DIN-rail or panel-mount enclosures.

The SENTRON 3VA series carries IEC and UL certifications; the IP40 front protection class and 800 V rated insulation voltage are documented in the manufacturer's device manual. RoHS and REACH compliance are standard for current-production Siemens SENTRON breakers.

Frequently asked questions

Where can I buy 3VA1181-6MG32-0AA0 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time, not before.

What is the interrupting capacity of 3VA1181-6MG32-0AA0 at 240 V?

220 kA at 240 V — that is the highest interrupting rating on this breaker, suitable for high-fault-current installations at that voltage level.

What compliance documentation does this breaker carry?

The SENTRON 3VA series is designed to IEC and UL standards; RoHS and REACH compliance is standard for current-production Siemens MCCBs. The IP40 front protection class and 800 V rated insulation voltage are documented in the device manual.
