At 55 °C it holds 488 A, at 60 °C it holds 476 A, and at 65 °C it holds 464 A — the thermal curve is published, so you can size it for elevated ambient inside a closed panel without guessing. No ground-fault monitoring, no undervoltage release, no communication function on this variant: it is a straight feeder or main breaker for a distribution panel where upstream coordination and downstream selectivity are handled by the trip curve alone. Breaking capacity is spec'ed per voltage: 187 kA at 240 V AC, 121 kA at both 415 V and 440 V AC, and 76 kA at 500 V AC. Physical footprint: 138 mm wide, 248 mm tall, 110 mm deep. Maximum power dissipation is 123 W at rated load — factor that into your enclosure thermal calculation.","metaTitle":"Siemens 3VM1450-5EE32-0AA0 SENTRON MCCB, 500 A, 3-Pole, TM22","metaDescription":"Siemens SENTRON 3VM1450-5EE32-0AA0 molded case circuit breaker, 500 A rated at 40 °C, 3-pole, TM220 release. 187 kA at 240 V.
