Product details

The Siemens SENTRON 3VA1020-3ED32-0CH0 is a 3-pole molded case circuit breaker (MCCB) rated for 20 A continuous current across its full ambient temperature range from 40 °C to 55 °C, derating only to 19 A at 60 °C through 70 °C. Its breaking capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V — so it handles high-fault industrial mains without cascading upstream.

At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB fits standard SENTRON 3VA panel footprints and mounts on a DIN rail or directly to a backplate. The 14.5 W heat dissipation means you should allow natural convection clearance in the enclosure.

Frequently asked questions

How do I get current pricing and availability for 3VA1020-3ED32-0CH0?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time from independent distribution channels.

Will 3VA1020-3ED32-0CH0 drop into a panel specified around 3VA1110-5ED36-0AC0 without rewiring?

The 3VA1020 is a 20 A, 3-pole MCCB with an undervoltage release; the 3VA1110 is a higher-rated variant. Both share the SENTRON 3VA family footprint (70 mm depth, 76.2 mm width, 130 mm height), so the panel cutout and DIN-rail mounting are the same — but verify the load rating and release wiring because the 3VA1110 carries a different current frame and may lack the UVR.

What compliance documentation does this brand provide for 3VA1020-3ED32-0CH0?

Siemens SENTRON series MCCBs typically carry IEC 60947-2 certification, UL 489 listing, and CE marking. RoHS and REACH declarations are standard from the manufacturer.
