The interrupting capacity tells the real story: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. The TM240 release has an adjustable long-time delay (tr max 1 s) for coordinating with downstream feeders. ## Thermal derating — the real-world current you can actually pull At 55 °C it derates to 153.6 A, at 60 °C to 150.4 A, at 65 °C to 147.2 A, and at 70 °C to 144 A. ## Physical fit and auxiliary contacts If you need any of those, you're looking at a different variant or an add-on accessory.","metaTitle":"Siemens 3VA1116-5EF32-0AF0 SENTRON MCCB, 160 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA1116-5EF32-0AF0 molded case circuit breaker, 160 A rated, 187 kA at 240 V interrupting capacity.
