Product details

MCCB for line protection — 32 A, 4-pole, high breaking capacity

The Siemens SENTRON 3VA1132-4EF46-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for 32 A continuous at 40 °C, with a TM240 thermal-magnetic trip unit designed for line protection — meaning it protects cables and distribution buswork from overload and short-circuit faults, not motor loads. The 121 kA breaking capacity at 240 V gives substantial SCCR headroom for high-fault panels; at 415 V it still interrupts 75.6 kA, and at 690 V it holds 11.9 kA.

Integration — panel fit and mounting

Its 101.6 mm width (4 in) and 70 mm depth (2.76 in) fit standard MCCB panel cutouts; height is 130 mm (5.12 in).

Frequently asked questions

Who supplies 3VA1132-4EF46-0AA0 and how is it quoted for volume purchases?

This MCCB is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What is 3VA1132-4EF46-0AA0's breaking capacity at different voltages?

121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.

What is the temperature derating for this 32 A MCCB?

Rated 32 A continuous from 40 °C to 50 °C, then derates to 31 A at 55–60 °C, and 30 A at 65–70 °C.
