Product details

MCCB for line protection — 20 A, 3-pole, 220 kA SCCR

The Siemens SENTRON 3VA1120-6EF32-0AE0 is a 3-pole molded case circuit breaker rated for 20 A continuous current with a TM240 thermal-magnetic release, delivering 220 kA interrupting capacity at 240 V and 154 kA at 415 V — sufficient for high-fault panelboard and distribution applications where upstream coordination demands a robust SCCR. Rated insulation voltage is 800 V, and the breaker carries 4 HQ auxiliary switches for status feedback to a PLC or annunciator — no undervoltage release, no communication module, no ground-fault monitoring on this variant.

Thermal derating and ambient range

Full 20 A rating holds through 50 °C; above that it derates linearly to 18 A at 70 °C. Operating ambient spans -25 °C to 70 °C, storage from -40 °C to 80 °C. The front face carries IP40 protection — suitable for dry indoor panel environments, not washdown zones.

Mounting and dimensions

Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — fits standard panel-mount cutouts for SENTRON 3VA frames. The 4 HQ auxiliary switches are factory-installed; no field-add kit needed for basic status feedback.

Frequently asked questions

Where can I buy 3VA1120-6EF32-0AE0 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time, not a stock promise.

What is 3VA1120-6EF32-0AE0's interrupting capacity at 415 V?
