It's built for line protection — the standard job of clearing overloads and short circuits in distribution panels, motor control centers, and feeder circuits. The 63 A rating holds steady up to 50 °C; above that it derates gradually, dropping to 56.7 A at 70 °C, so if your panel runs hot, size up accordingly. Breaking capacity is the headline here: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. That's high-interrupting capability — enough for most industrial service-entrance or sub-distribution applications where fault current runs high. The 415 V figure in particular (75.6 kA) covers common 400 V-class installations with substantial transformer capacity behind them. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits Siemens SENTRON panelboards and most DIN-rail or base-mount enclosures. That keeps it simple and reliable for basic overcurrent protection, but if you need adjustable long-time or short-time pickup curves, you'd step up to the electronic-trip variants in the 3VA family. ## What's on the auxiliary side If you need one of those, the 3VA platform supports field-installable accessory modules, but this order code ships without them. The 15 000 mechanical endurance cycles are typical for an MCCB in distribution duty — not a frequent-switching device, but fine for panel isolation and backup protection.","metaTitle":"Siemens 3VA1163-4EF32-0AB0 SENTRON MCCB, 63 A, 3-Pole, TM240","metaDescription":"Siemens 3VA1163-4EF32-0AB0 SENTRON molded case circuit breaker, 63 A rated continuous current, 3-pole, TM240 thermal-magnetic release.
