Product details

It carries a 40 A thermal-magnetic trip unit (TM240) at 40 °C ambient, holds the full 40 A through 50 °C, then derates to 37 A at 70 °C — so in a warm enclosure you lose only a few amps off the top. Breaking capacity hits 75.6 kA at 240 V AC, 52.5 kA at 415 V, and still delivers 11.9 kA at 690 V, giving you solid SCCR headroom for most industrial feeds. No ground-fault module, no communication function; this is a straight thermal-magnetic MCCB with a UVR add-on.

Width is 76.2 mm (3 in), depth 70 mm (2.76 in), height 130 mm (5.12 in) — standard 3-pole MCCB footprint for a 40 A frame. No trip indicator, no voltage trigger — if you need visual trip indication, factor in an auxiliary contact separately.

Breaking capacity across voltages

At 440 V: 32 kA. That curve tells you the breaker is most comfortable on 240–415 V systems where it has massive fault-clearing headroom; at 690 V it still handles 11.9 kA, enough for most 690 V motor feeds unless you're near a large transformer.

Frequently asked questions

What is the breaking capacity of 3VA1140-3EF36-0CA0 at 415 V?

52.5 kA at 415 V AC, which covers most industrial distribution fault levels at that voltage.

Does 3VA1140-3EF36-0CA0 include an undervoltage release?

Yes, it ships with a factory-fitted undervoltage release (UVR) for automatic trip on control-voltage loss.

Where can I buy 3VA1140-3EF36-0CA0?

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