That 63 A holds steady through most panel environments — you don't lose headroom until the cabinet runs hot. The interrupting rating is the standout: 187 kA at 240 V, 121 kA at 415 V, still 76 kA at 440 V. That puts it in high-fault territory — suitable for main or tie breakers in large distribution boards where available fault current is serious. The TM220 thermal-magnetic trip unit gives fixed thermal and magnetic settings — no adjustment dials, which means less to go wrong and no risk of mis-setting in the field. The auxiliary contact package is 1 NO/NC auxiliary switch plus 1 separate trip-alarm switch (HQ type), so you get both status and fault indication without adding external relays. ## Panel fit — 130 mm tall, 3 in wide, IP40 front At 130 mm height and 3-inch width, this breaker fits the standard SENTRON 3VA footprint. The 15 000 mechanical endurance cycles (latching) cover most industrial switching duty without premature wear.","metaTitle":"Siemens 3VA1110-4EE36-0AF0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1110-4EE36-0AF0 molded case circuit breaker, 63 A continuous, 187 kA interrupting at 240 V.
