Rated interrupting capacity reaches 220 kA at 240 V AC and 154 kA at 415 V AC, dropping to 17 kA at 500 V and 690 V — the SCCR headroom at lower voltages makes this breaker suitable for high-fault-capacity main or subfeed positions where coordination with upstream gear is critical. The 70 mm depth by 76.2 mm width footprint fits standard 3-pole MCCB panel cutouts and DIN-rail adapter plates; the 130 mm height clears typical enclosure gland plates without interference. ## Thermal Derating and Ambient Performance At 55 °C it derates to 49 A, at 60 °C to 48 A, at 65 °C to 46 A, and at 70 °C to 45 A. For a panel running warm — say 55 °C internal ambient — the breaker still carries 49 A continuous, which is within typical design margins for a 50 A feeder. ## Configuration and Auxiliary Switching","metaTitle":"Siemens 3VA1150-6EF36-0AC0 SENTRON MCCB, 50 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1150-6EF36-0AC0 molded case circuit breaker, 50 A rated at 40 °C, 3-pole, 220 kA at 240 V.

The difference is in the release and rating — this unit carries a 50 A TM240 thermal-magnetic release versus the lower-rated release on the 3VA1110 variant.
