Above 50 °C the rating steps down linearly: 488 A at 55 °C, 476 A at 60 °C, 464 A at 65 °C, and 452 A at 70 °C. Breaking capacity is specified per voltage: 121 kA at 240 V AC, 76 kA at 415 V and 440 V AC, and 53 kA at 500 V AC. That gives solid fault-clearing headroom for most low-voltage distribution panels on common industrial supply voltages. It uses a TM210 thermal-magnetic overcurrent release — a fixed-trip design with no electronic adjustment, suited for straightforward line protection where you want a reliable, non-programmable trip curve. That 110 mm depth (4.33 in) is the projection behind the panel face — check your enclosure depth before committing the mounting plate. The trip indicator is also absent, so visual trip status comes from the handle position only. The storage spec governs handling and warehousing, not running conditions.","metaTitle":"Siemens 3VM1450-4ED32-0AA0 SENTRON MCCB, 500 A, 3-Pole, TM21","metaDescription":"Siemens SENTRON 3VM1450-4ED32-0AA0 molded case circuit breaker, 500 A continuous at 40-50 °C, 3-pole, TM210 release, 121 kA at 240 V AC.
