It carries a TM240 thermal-magnetic release — the thermal element handles overloads, the magnetic element clears short-circuits. Breaking capacity reaches 220 kA at 240 V, dropping to 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V. That 220 kA figure at 240 V means it can safely interrupt a fault current up to that level without the arc flashing over or the case rupturing — critical for high-fault installations like transformer secondaries or large busway feeds. Rated insulation voltage Ui is 800 V, and the breaker carries a front-face IP40 rating — suitable for enclosed panel mounting where the front is operator-accessible but the live parts are behind a door. The auxiliary contact configuration is 2 auxiliary switches plus 1 trip alarm switch (HQ), which gives separate signaling for breaker position and fault condition. A shunt trip release (STL) is integrated for remote tripping; the integrated auxiliary trip is order code 3VA9688-0BL32. No undervoltage release, no communication function, no phase failure detection, and no ground fault monitoring are fitted on this variant — it is a straight line-protection MCCB. ## Thermal Derating and Operating Range The 200 A rating holds flat from 40 °C through 50 °C ambient. Above that, derating is linear: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. If the panel ambient runs above 50 °C — common in tightly packed switchgear or near transformer vaults — size the breaker for the derated value, not the nameplate 200 A. Operating ambient range is -25 °C to +70 °C; storage range is -40 °C to +80 °C. Mechanical endurance is rated at 15 000 operations. ## Panel Integration and Mounting Dimensions are 105 mm wide, 158 mm high, and 70 mm deep. The 3-pole frame mounts on a DIN rail or directly to a backplate via the screw terminals. Front-face IP40 means it is protected against solid objects larger than 1 mm on the operator side, but the enclosure must provide the overall IP rating for the panel. The trip indicator and voltage trigger are present on the front for visual status. Reference code per DIN EN 81346-2 is Q.","metaTitle":"Siemens 3VA1220-6EF32-0JH0 SENTRON MCCB, 200 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1220-6EF32-0JH0 molded case circuit breaker, 200 A rated, 3-pole, line protection.
