It carries an interrupting capacity of 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 11.9 kA at 690 V — so it can handle high-fault scenarios on distribution or feeder circuits without cascading upstream. Above that it derates linearly: 488 A at 55 °C, 476 A at 60 °C, 464 A at 65 °C, and 452 A at 70 °C. The 3-pole footprint is standard for this class — check gland-plate clearance for the 110 mm depth, especially in shallow enclosures.","metaTitle":"Siemens 3VA1450-5EE32-0AA0 SENTRON MCCB, 500 A, 3-Pole, TM22","metaDescription":"Siemens 3VA1450-5EE32-0AA0 SENTRON molded case circuit breaker, 500 A continuous, 3-pole, TM220 release, 187 kA at 240 V.
