That means on a 480 V panel this breaker still holds a solid 121 kA SCCR — plenty for most industrial distribution boards. Rated current holds at 50 A from 40 °C up to 50 °C, then derates gradually: 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, 45 A at 70 °C. Maximum power loss is 14.6 W, which matters for thermal budgeting in a sealed enclosure. It's a straight line-protection MCCB: install it, feed a bus, and rely on the TM240 release to do its job without extras.","metaTitle":"Siemens 3VA1150-6EF36-0AA0 SENTRON MCCB, 3-pole, 50 A, 220 k","metaDescription":"Siemens SENTRON 3VA1150-6EF36-0AA0 molded case circuit breaker, 3-pole, 50 A rated current, 220 kA breaking capacity at 240 V.

The difference is the rating: this one is 50 A with a TM240 release; the 3VA1110-5EE36-0AA0 is a lower-current variant. If the panel bus and load calcs support 50 A, it's a direct mechanical swap without rewiring."},{"question":"How do I get current pricing and availability for 3VA1150-6EF36-0AA0?","answer":"Submit an RFQ against this order code.
