Product details

Siemens SENTRON 3VA1040-3ED32-0KA0 — 40 A MCCB with Shunt Trip

It carries 40 A continuously at 40 °C ambient, with no derating needed until you cross 55 °C — at 55 °C it still holds 38.4 A, and at 70 °C it holds 36 A. Interrupting capacity is the headline: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 500 V and 690 V. The TM210 overcurrent release handles the trip curve; there's no ground-fault module on this variant.

Shunt Trip and Panel Fit

The shunt trip is factory-fitted; no field-kit installation needed. The breaker is 76.2 mm wide, 130 mm tall, and 70 mm deep — standard 3-pole MCCB footprint for DIN-rail or panel-mount enclosures.

Frequently asked questions

What is the interrupting capacity of this MCCB at 240 V?

75.6 kA at 240 V, with 52.5 kA at 415 V and 32 kA at 440 V.

Does this breaker include a shunt trip or undervoltage release?

It includes a factory-fitted shunt trip release (STL) for remote tripping. There is no undervoltage release on this order code.

Where can I buy 3VA1040-3ED32-0KA0 and how is it quoted?
