Product details

Breaking capacity varies sharply with system voltage: 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.

Above 50 °C it begins to derate: 39 A at 55 °C and 60 °C, 38 A at 65 °C, 37 A at 70 °C. Physical footprint is 130 mm height, 76.2 mm width, 70 mm depth — a compact 3-pole MCCB that fits standard panel-mount cutouts. Maximum power loss at rated load is 13.3 W; factor that into your enclosure thermal budget, especially in sealed cabinets.

Because it is an active catalog item, the normal Siemens distribution channel carries it. No minimum commitment required for a single-line BOM fill.

Frequently asked questions

What is the breaking capacity of 3VA1140-4EF36-0BA0 at 415 V?

75.6 kA at 415 V AC. At 240 V it reaches 121 kA; at 690 V it drops to 11.9 kA.

Does 3VA1140-4EF36-0BA0 include an undervoltage release?

Yes, it is equipped with an undervoltage release (UVR) as standard. The UVR will trip the breaker if control voltage drops below its dropout threshold.

Where can I buy 3VA1140-4EF36-0BA0 and what is the lead time?

We source this active Siemens MCCB to order against an RFQ. Availability and current pricing are confirmed at quote time through our independent distribution channels.
