The TM220 designation means the thermal element is fixed at 63 A (the frame rating) and the magnetic short-circuit pickup is adjustable from 5× to 10× In — so you set the instantaneous trip threshold between 315 A and 630 A to coordinate with downstream devices. Breaking capacity reaches 187 kA at 240 V AC, dropping to 121 kA at 415 V and 75.6 kA at 440 V, which covers most industrial service-entrance and distribution panel applications where high fault current is expected. Above that, derating is gradual: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. Maximum power dissipation is 17.3 W at rated load, which matters for thermal coordination inside a sealed enclosure.","metaTitle":"Siemens 3VA1163-5EE32-0AA0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1163-5EE32-0AA0 molded case circuit breaker, 63 A rated, 3-pole, TM220 release.
