It is designed for line protection — the primary feeder or distribution breaker in a panel — not for motor starter duty or ground-fault monitoring. Breaking capacity is the headline: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The 4-pole width (101.6 mm) is standard for a 4-pole MCCB in this frame size; verify the existing panel cutout if replacing a different brand. The TM220 trip is a fixed thermal-magnetic — no electronic adjustment or zone-selective interlocking. At 55 °C it derates to 62 A, at 60 °C to 61 A, at 65 °C to 60 A, and at 70 °C to 58 A. Maximum power loss is 17.3 W at rated current — negligible for panel thermal budgeting but worth noting for tightly packed enclosures.","metaTitle":"Siemens 3VA1163-4EE42-0AA0 SENTRON MCCB, 63 A, 4-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1163-4EE42-0AA0 molded case circuit breaker, 63 A continuous, 4-pole, TM220 trip, 121 kA at 240 V.
