For a panel builder, that's the difference between a coordinated selective system and a cascade failure that takes out the main breaker too. The TM240 thermal-magnetic release is fixed-trip, so you're not fiddling with adjustment knobs. What you set at the factory is what it opens at. Rated continuous current Iu is 125 A, and the insulation voltage Ui is rated 800 V — that's the voltage the guts are designed to withstand without tracking or flashover. ## Thermal derating — the real-world curve At 55 °C it drops to 120 A, then 117.5 A at 60 °C, 115 A at 65 °C, and 112.5 A at 70 °C. If your panel sits next to a hot motor drive or a solar combiner box, that's the number you need for the BOM — not the catalog nominal. Out here in the grease, I've buried plenty of breakers that looked good on paper but tripped early because nobody checked the ambient column. ## Built for a panel, not a lab bench","metaTitle":"Siemens 3VA1112-6EF36-0DC0 SENTRON MCCB, 125A, 240V 220kA","metaDescription":"Siemens 3VA1112-6EF36-0DC0 SENTRON molded case circuit breaker. 125A continuous, 220 kA at 240 V.
