Product details

Rated 50 A continuously from 40 °C up to 50 °C, derating to 45 A at 70 °C. Breaking capacity is the headline: 220 kA at 240 V AC, 154 kA at 415 V, 121 kA at 440 V, and still 17 kA at 690 V.

The 4-pole width (101.6 mm) is standard for a 4-pole MCCB in this frame size — it drops into a panel designed for a 4-pole SENTRON 3VA breaker without re-drilling the mounting plate. Rated insulation voltage 800 V, power loss 14.6 W max.

What the TM240 trip unit means

TM240 is a thermal-magnetic release: the thermal element protects against sustained overloads (inverse-time curve), the magnetic element handles short-circuit instantaneously. If you need ground-fault or shunt-trip, this isn't the order code for that.

Frequently asked questions

Where can I buy 3VA1150-6EF46-0AA0 and get a price?

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

What is the breaking capacity of 3VA1150-6EF46-0AA0 at 415 V?

154 kA at 415 V AC. At 240 V it's 220 kA, at 440 V it's 121 kA, and at 690 V it holds 17 kA.

Will 3VA1150-6EF46-0AA0 drop into a panel designed for 3VA1110-5EE36-0AA0?

Both are 4-pole SENTRON 3VA breakers in the same frame size, so the mounting footprint and bus-bar spacing are identical. The difference is the trip unit and rating — this one is TM240 at 50 A, while the 3VA1110-5EE36-0AA0 carries a different release. No rewiring needed for the physical fit.
