It carries a TM220 thermal-magnetic overcurrent release — the thermal element handles overloads, the magnetic element clears short-circuits. Breaking capacity is voltage-dependent: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. That spread tells you the real-world fault current it can interrupt drops as system voltage rises — at 690 V you're limited to 17 kA, so verify your available fault current at that voltage before specifying. ## Thermal derating and operating envelope The 63 A rating holds flat from 40 °C through 50 °C. Above that it derates: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. If your panel ambient runs hot — say a sealed enclosure near a furnace line — you lose 5 A by the time you hit 70 °C. The operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Power loss at full load is 17.3 W, which matters for enclosure thermal calculations when you stack several breakers side by side. ## Physical fit and panel integration Dimensions are 130 mm high, 101.6 mm wide, 70 mm deep. The 70 mm depth is the body only — allow additional clearance for rear terminals and arc-chamber venting per Siemens mounting instructions. IP40 on the front face means it's protected against tools and wires >1 mm, but not against moisture; keep it inside a rated enclosure. Rated insulation voltage is 800 V AC; max DC operational voltage is 600 V. The design accepts an optional motor drive (product extension available), so remote trip or reset is possible without replacing the breaker.","metaTitle":"Siemens 3VA1163-5EE42-0AA0 SENTRON MCCB, 63 A, 4-Pole, 187 k","metaDescription":"Siemens 3VA1163-5EE42-0AA0 SENTRON molded case circuit breaker, 63 A, 4-pole, 187 kA at 240 V.
