Product details

The interrupting capacity reaches 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V, making it suitable for high-fault panels where SCCR headroom matters.

At 690 V the breaker still clears 7.5 kA, which covers most industrial motor-drive circuits at that voltage level. Maximum power loss is 14.5 W — a figure to check against enclosure thermal rise in a densely packed panel.

Built-in undervoltage release

No ground-fault monitoring or communication module is fitted; this is a straight line-protection MCCB.

The case measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON distribution panels without re-drilling the gland plate.

Frequently asked questions

How do I get current pricing and availability for 3VA1020-3ED36-0DC0?

Submit an RFQ through this listing. The part is sourced and quoted to order through independent distribution; availability and current pricing are confirmed at quote time.

Will 3VA1020-3ED36-0DC0 drop into a panel specified around 3VA1020-3ED36-0AA0 without rewiring?

Yes, the physical dimensions are identical — 130 mm high, 76.2 mm wide, 70 mm deep — so it occupies the same panel footprint and mounting hole pattern. The functional difference is the built-in undervoltage release on the -0DC0 variant versus the -0AA0 which lacks it. If the original panel wiring included the UVR coil connections, the swap is direct; if not, you need to add those two wires.

What compliance documentation does this brand provide for 3VA1020-3ED36-0DC0?

Siemens SENTRON MCCBs carry UL, CSA, and CE certifications as standard. RoHS and REACH declarations are available from the manufacturer's documentation portal. Specific certificate numbers should be confirmed against the nameplate marking on the unit received.
