Product details

Its interrupting capacity reaches 75.6 kA at 240 V and 52.5 kA at 415 V, making it suitable for high-fault-current distribution panels where selectivity and SCCR headroom are specified.

Above that, the TM210 release begins to derate: 19.2 A at 55 °C, 18.8 A at 60 °C, 18.4 A at 65 °C, and 18 A at 70 °C.

Interrupting capacity by system voltage

The interrupting ratings span the common industrial voltages: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V.

No auxiliary contacts are fitted on this variant; if remote status indication is needed, the 3VA9608-0BB11 auxiliary trip is the only integrated switch.

Frequently asked questions

How do I get current pricing and availability for 3VA1020-3ED36-0BA0?

Submit an RFQ through the storefront. Pricing and stock are confirmed at quote time; no real-time figures are published here.

When sourcing 3VA1020-3ED36-0BA0, what's the closest functional second-source — 3VA1020-3ED36-0AA0?

The 3VA1020-3ED36-0AA0 is the same frame and release but without the undervoltage release. It drops into the same panel footprint and wiring — the only difference is the UVR coil and its associated trip mechanism. If the BOM calls for undervoltage protection, the -0BA0 is the correct variant; the -0AA0 would need a separate undervoltage relay added.

What is 3VA1020-3ED36-0BA0's listed depth (70 mm) on this component line?

The depth is 70 mm, measured from the mounting surface to the front of the breaker body — not including any protruding handle or auxiliary trip module.

What is 3VA1020-3ED36-0BA0's listed width (76.2 mm) on this component line?

The width is 76.2 mm, which is the standard 3-pole SENTRON 3VA10 frame width. It occupies three 25.4 mm pole spaces on a DIN rail.

Will 3VA1020-3ED36-0BA0 drop into a panel that was specified around 3VA1020-3ED36-0AA0 without rewiring?

Yes — the two variants share the same frame dimensions, same terminal layout, and same 20 A TM210 release. The only difference is the integrated undervoltage release on the -0BA0. If the panel was wired for the -0AA0 (no UVR), the -0BA0 will bolt in, but the UVR coil terminals must be connected to the control voltage that will trip the breaker on loss of power. If no UVR connection is made, the breaker functions as a standard thermal-magnetic MCCB.
