The Siemens SENTRON 3VM1450-5EE32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 500 A across the 40 °C to 50 °C band without derating. 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.

Frequently asked questions
Where can I buy 3VM1450-5EE32-0AA0 and get a price?
Sourced and quoted to order against an RFQ through authorized distribution. Availability and current pricing are confirmed at quote time.
What is the breaking capacity of 3VM1450-5EE32-0AA0 at 240 V?
187 kA at 240 V AC. At 415 V and 440 V it is 121 kA; at 500 V it is 76 kA.
What does the TM220 release designation mean?
TM220 is a thermal-magnetic overcurrent release. The thermal element provides time-delayed overload protection; the magnetic element provides instantaneous short-circuit protection. No ground-fault or undervoltage functions are included on this variant.
What is the physical size of 3VM1450-5EE32-0AA0?
Width 138 mm, height 248 mm, depth 110 mm.
Does 3VM1450-5EE32-0AA0 support communication or ground-fault monitoring?
No. This variant has no communication function, no ground-fault monitoring, no undervoltage release, and no voltage trip. It is a straight line-protection MCCB.
