Breaking capacity at 240 V is 75.6 kA, dropping to 52.5 kA at 415 V and 32 kA at 440 V; at 500 V and 690 V it holds at 11.9 kA. Mounts on DIN rail or panel. The 3-pole footprint matches standard SENTRON 3VA1 family cutouts. The UVR coil terminals are on the left side; verify free-wheel diode polarity on the control circuit before energizing. No auxiliary contacts are included — order separately if remote status is needed. Power dissipation at rated load is 14.5 W max; allow airflow in the enclosure to avoid cumulative heat rise above 70 °C operating limit. ## Delta: 3VA1020-3ED36-0AA0 The closest functional sibling is the 3VA1020-3ED36-0AA0. Both are 3-pole SENTRON MCCBs with TM releases and UVR. The 3VA1020 frame has a lower interrupting rating — typically 25 kA at 415 V vs. this unit's 52.5 kA — and a different trip curve (ED vs. EF). Physically, the 3VA1120 is 76.2 mm wide vs. the 3VA1020's 70 mm; check panel cutout compatibility before swapping.","metaTitle":"Siemens SENTRON 3VA1120-3EF36-0CA0 MCCB, 3-pole, 75.6 kA at","metaDescription":"Siemens SENTRON 3VA1120-3EF36-0CA0 molded case circuit breaker, 3-pole, line protection, TM240 release, 75.6 kA at 240 V.
