Above that it steps down: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C (–). That matters if this breaker sits near transformers or drives inside a hot enclosure — you don't lose half your capacity, but you do lose 12 % at the top of the range. The maximum power loss of 42 W is manageable for a 200 A frame, but it's heat that needs to leave the panel. ## What the TM220 release means The TM220 designation tells you this is a thermal-magnetic release with a fixed thermal pickup and a magnetic trip that responds to short-circuit current. It's line-protection design, not motor-protection — no adjustable overload curve for starting inrush. Use it for feeder circuits, distribution panels, and cable protection where the load is resistive or the motor has its own overload relay downstream.","metaTitle":"Siemens 3VM1220-5EE32-0AA0 SENTRON MCCB, 200 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VM1220-5EE32-0AA0 molded case circuit breaker, 200 A, 3-pole, 187 kA IC at 240 V AC.
