The thermal-magnetic trip unit means no external power needed for overcurrent sensing; the TM240 designation sets the thermal pickup at 200 A with magnetic instantaneous trip calibrated for the frame. No undervoltage release, no communication module, no phase-failure detection — this is a straightforward thermal-magnetic MCCB for standard distribution panels, not a smart or communicating device. ## Current-carrying capacity across the temperature range At 55 °C it derates to 194 A, then 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. Front protection is IP40, so it's splash-resistant on the face but not sealed for washdown environments. Dimensions: 105 mm wide, 158 mm high, 70 mm deep. Three-pole frame mounts in standard distribution panel cutouts.","metaTitle":"Siemens 3VA1220-4EF32-0HH0 SENTRON MCCB, 200 A, 3-Pole, 121","metaDescription":"Siemens SENTRON 3VA1220-4EF32-0HH0 molded case circuit breaker, 200 A, 3-pole, 121 kA at 240 V.
