Product details

The Siemens SENTRON 3VA2140-5MN32-0KL0 is a 3-pole molded case circuit breaker (MCCB) rated 40 A continuously from 40 °C up through 70 °C ambient — no derating needed across that span, which simplifies panel design in warm enclosures. The motor-protection design includes phase failure detection, so it catches a lost phase before the winding overheats.

Built-in accessories — shunt trip and auxiliary switches

That covers remote status indication and emergency-off integration without adding external relay logic. The trip indicator and voltage trigger are present, so a downstream PLC or SCADA gets a clear signal on the event.

At 86 mm deep, 105 mm wide, and 181 mm tall, the 3VA2140-5MN32-0KL0 fits the standard SENTRON 3VA footprint. Panel cutout and bus-bar spacing match the 3VA family — no re-drilling if you are swapping from another 3VA frame. The 3-pole block occupies a single mounting position in a distribution board or motor control center.

Frequently asked questions

What is the breaking capacity of 3VA2140-5MN32-0KL0 at 415 V?

The interrupting rating is 121 kA at 415 V. At 240 V it reaches 187 kA; at 500 V it drops to 75.6 kA; at 690 V it is 3.7 kA.

Where can I buy 3VA2140-5MN32-0KL0?

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

Does 3VA2140-5MN32-0KL0 include a shunt trip?

Yes, the design of the auxiliary release includes a shunt trip (STL). It also ships with two auxiliary switches, one trip alarm switch, and one electrical alarm switch HQ.
