This part carries a lifecycle status of current, meaning Siemens still actively manufactures it. No last-time-buy notice, no successor code to track. For a BOM line that needs a 50 A MCCB with a TM210 release and a 3-pole footprint, this is the direct order code — not a cross-reference or a second-source. The front face carries an IP40 rating, so it is fine for a typical IP54 or IP65 enclosure as long as the door protects it from direct water jets. ## Thermal performance across temperature At 55 °C it drops to 49 A, at 60 °C to 48 A, at 65 °C to 46 A, and at 70 °C to 45 A. Maximum power loss is 14.6 W at full load — negligible for thermal budgeting in most enclosures.","metaTitle":"Siemens 3VA1150-5ED36-0AA0 SENTRON MCCB, 50 A, 187 kA at 240","metaDescription":"Siemens 3VA1150-5ED36-0AA0 SENTRON molded case circuit breaker, 3-pole, 50 A, TM210 release, 187 kA at 240 V.
