Product details

The Siemens 3VA1132-4EF32-0KA0 is a 3-pole SENTRON molded case circuit breaker rated for 32 A continuous current (Iu) at 40 °C, with the TM240 thermal-magnetic overcurrent release. Breaking capacity runs 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V — so it clears high-fault downstream of a transformer or upstream of a distribution panel without cascading failure.

Current derating — what the thermal curve means for your panel

At 55 °C it drops to 30.72 A, at 60 °C to 30.08 A, at 65 °C to 29.44 A, and at 70 °C to 28.8 A.

Integrated shunt trip and auxiliary options

The integrated auxiliary trip uses order code 3VA9688-0BL33 if you need a spare or replacement.

Frequently asked questions

What is the breaking capacity of 3VA1132-4EF32-0KA0 at 415 V?

At 415 V the breaking capacity is 75.6 kA.

What does the TM240 overcurrent release mean?

TM240 is a thermal-magnetic release — the thermal element protects against overload (trip curve follows the 32 A rating), and the magnetic element handles short-circuit protection up to the listed breaking capacities.

Does 3VA1132-4EF32-0KA0 include a shunt trip?

Yes, it ships with a shunt trip (STL) auxiliary release integrated.

How do I get current pricing and availability for 3VA1132-4EF32-0KA0?

Submit an RFQ — the part is sourced to order through independent distribution, and current pricing and availability are confirmed at quote time.

Will 3VA1132-4EF32-0KA0 drop into a panel specified around 3VA1010-2ED32-0JA0 without rewiring?

Both are 3-pole SENTRON MCCBs with the same 76.2 mm width and 130 mm height, so the footprint and bus-bar centers match. The 3VA1132-4EF32-0KA0 carries a higher 32 A rating and a shunt trip, while the 3VA1010-2ED32-0JA0 is a lower-current variant — verify the load current and auxiliary requirements before swapping.
