That 500 A frame holds across most panel ambient conditions you will see in a switchroom — you only lose 20 A by the time the enclosure hits 70 °C, so the thermal margin is generous for a 500 A feeder or motor branch. Three poles, motor protection version with an ETU350M electronic trip unit. The ETU350M gives you adjustable thermal and magnetic protection curves, plus a trip indicator on the front so you can tell at a glance whether it opened on overload or short-circuit. Breaking capacity is 330 kA at 240 V, 242 kA at 415 V and 440 V, and 52.5 kA at 690 V. The 690 V figure of 52.5 kA still covers heavy motor circuits on 690 V distribution. Front protection is IP40 — suitable for clean indoor switchgear. That covers most PLC or SCADA status inputs without adding a second auxiliary block. Maximum power loss is 99 W at rated current. Mechanical endurance is 15,000 operations, which is typical for a fixed-mounted MCCB in a distribution board; not a switching duty cycle for frequent motor starting.","metaTitle":"Siemens 3VA2450-7MN32-0AH0 MCCB, 500 A, 3-Pole, ETU350M","metaDescription":"Siemens SENTRON 3VA2450-7MN32-0AH0 molded case circuit breaker, 500 A, 3-pole, ETU350M release, 330 kA at 240 V.
