Its interrupting capacity reaches 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — figures that place it in the high-fault-current tier for industrial distribution panels and motor control centers. This MCCB is dimensioned at 130 mm height, 76.2 mm width, and 70 mm depth — a 3-pole footprint that fits standard SENTRON panel-mount cutouts. Front-side IP40 protection covers the operator interface; the enclosure itself is rated for panel interior use, not washdown zones. Above that, derating begins: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. For a panel pulling near the 63 A limit at an ambient above 50 °C, the effective continuous current drops — factor this into load schedules. ## Undervoltage release and auxiliary options This variant includes an undervoltage release (UVR) — the auxiliary release type is designated as 3VA9608-0BB25. No auxiliary contacts are fitted on this order code; no communication module, no phase-failure detection, no ground-fault monitoring. If remote signaling or status feedback is needed, the auxiliary contact kit is a separate add-on.","metaTitle":"Siemens 3VA1163-6EF36-0DA0 SENTRON MCCB, 63 A, 220 kA at 240","metaDescription":"Siemens SENTRON 3VA1163-6EF36-0DA0 molded case circuit breaker, 3-pole, 63 A rated current, 220 kA breaking capacity at 240 V.
