At 240 V this breaker can interrupt 187 kA — that's well above what most commercial panels see, so you're covered even on high-capacity transformer feeds. At 440 V it still clears 75.6 kA, and at 500 V or 690 V it holds at 17 kA. Those numbers mean the breaker can safely open under a dead short without welding contacts or blowing apart, which is what UL 489 and IEC 60947-2 certify for MCCBs. The thermal-magnetic TM240 release gives you fixed thermal pickup and magnetic trip settings tuned for cable and busbar protection — no field-adjustable dials to fumble with. ## Thermal derating and real-world loading At 55 °C it derates to 98 A, at 60 °C to 96 A, and at 65 °C to 94 A. At the max operating temp of 70 °C you're at 91 A. That's a gentle slope — you can push it near full rating in a warm panel without oversizing. Power loss at full load runs 27.5 W, so heat buildup is manageable in a standard enclosure with moderate airflow.","metaTitle":"Siemens 3VA1110-5EF32-0CH0 SENTRON MCCB, 100 A, 3-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1110-5EF32-0CH0 molded case circuit breaker, 100 A continuous, 3-pole, TM240 thermal-magnetic release.
