Breaking capacity hits 121 kA at 240 V, 75.6 kA at 415 V, and still delivers 11.9 kA at 690 V. Footprint is 130 mm high by 76.2 mm wide by 70 mm deep — a compact 3-pole frame that fits standard MCCB mounting positions in SENTRON distribution boards or standalone enclosures. The 70 mm depth keeps the breaker clear of the gland plate in shallow backboxes. That means you get remote status indication and a remote-trip capability without ordering separate accessory kits — one order code covers the full switching and signaling chain. The 3VA series is Siemens' SENTRON molded-case platform, designed for UL 489 and IEC 60947-2 compliance. The breaker carries the standard approvals for North American and European installations — UL, CSA, and CE marking are inherent to the platform.","metaTitle":"Siemens 3VA1163-4EF36-0JH0 SENTRON MCCB, 63 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1163-4EF36-0JH0 molded case circuit breaker, 63 A rated at 40 °C, 121 kA breaking at 240 V. 3-pole, line protection, shunt trip.
