Product details

The interrupting capacity reaches 121 kA at 240 V and 75.6 kA at 415 V, which means it can safely clear high-fault currents on the secondary side of a distribution transformer without upstream fuse coordination failure.

Thermal-magnetic curve and derating across temperature

Above that, derating begins: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C.

Shunt trip and auxiliary contacts for remote control

The auxiliary release order code is 3VA9688-0BL30.

Front IP40 protection means it is suitable for enclosed panels but not for washdown zones.

Frequently asked questions

What is the interrupting capacity of 3VA1140-4EF32-0HC0 at different voltages?

The interrupting capacity is 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. These ratings cover most low-voltage distribution applications.

What does the TM240 release designation mean?

TM240 indicates a thermal-magnetic overcurrent release with a 40 A continuous current rating. The thermal element handles overload protection; the magnetic element provides instantaneous short-circuit protection.

Does this MCCB include a shunt trip or undervoltage release?

It includes a shunt trip (STL) for remote tripping. It does not include an undervoltage release or ground-fault monitoring. The auxiliary release order code for the shunt trip is 3VA9688-0BL30.

Where can I buy 3VA1140-4EF32-0HC0?

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