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.

Thermal derating and ambient range

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.
