Product details

It carries a continuous current rating of 50 A at 40 °C, derating to 45 A at 70 °C, so the thermal curve is what governs the real ampacity in a warm enclosure — don't size it at 50 A if the ambient inside the panel runs above 55 °C. The breaking capacity hits 52.5 kA at 240 V and 32 kA at 415 V, which covers most industrial service-entrance and feeder applications where fault currents are high.

Shunt trip and overcurrent release

Verify the busbar or lug kit spacing against the existing panel layout — the shunt trip adds no extra width, but the wiring for the STL control signal needs a separate pair of terminals.

Maximum power loss is 14.6 W at rated current. In a densely packed panel, that heat needs to be considered for the enclosure's thermal budget — especially if the breaker is mounted next to other heat-generating devices.

Frequently asked questions

Where can I buy 3VA1050-2ED42-0HA0 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Send your request with quantity and delivery target; availability and current pricing are confirmed at quote time.

What is 3VA1050-2ED42-0HA0's listed depth (70 mm) on this component line?

The depth is 70 mm (2.76 in), which is the standard depth for the 3VA1 frame size in this series.

What is 3VA1050-2ED42-0HA0's listed width (101.6 mm) on this component line?

The width is 101.6 mm (4 in), corresponding to the 4-pole housing width.

Will 3VA1050-2ED42-0HA0 drop into a panel that was specified around 3VA1010-2ED32-0AD0 without rewiring?

The 3VA1050-2ED42-0HA0 is a 50 A, 4-pole breaker with a shunt trip, while the 3VA1010-2ED32-0AD0 is a lower-current variant. The physical footprint (height, width, depth) is the same 3VA1 frame size, so it will mount in the same panel cutout and busbar spacing. However, the wiring must be sized for 50 A instead of the lower rating, and the shunt trip requires its own control wiring that the other variant may not have.
