The TM240 designation means the thermal element is fixed at 63 A (the frame rating), while the magnetic short-circuit pickup is set at 240 A — 3.8× the continuous rating, typical for motor branch circuits where inrush must ride through without nuisance tripping. The breaker carries a shunt trip auxiliary release (3VA9688-0BL32) integrated at the factory, so a remote trip signal can drop the load without pulling the handle. Breaking capacity varies by line voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. At 415 V — the common European industrial distribution level — the 52.5 kA rating comfortably exceeds the typical 25–36 kA prospective fault current in most panelboards, so this breaker can be applied downstream of a larger feeder without series-rating concerns. The 690 V figure (10.5 kA) covers 600 V class North American systems and 690 V European motor drives. Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm high — a standard 3-pole MCCB footprint that fits SENTRON panelboards and most DIN-rail adapter plates. Above 50 °C, the continuous current must be reduced: 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. The breaker is configured for line protection (not motor protection), meaning the TM240 thermal curve is matched to cable and busbar thermal limits rather than motor overload curves. If the load is a motor, a separate overload relay downstream is required. Sourcing is straightforward through independent distribution. No last-time-buy window is active, so there is no urgency to stockpile. The integrated shunt trip (3VA9688-0BL32) is a factory-fit option — if a panel calls for a field-installed shunt trip, the standard 3VA1163 without the -0JA0 suffix may be more economical.","metaTitle":"Siemens 3VA1163-3EF32-0JA0 SENTRON MCCB, 63 A, 3-Pole, TM240","metaDescription":"Siemens 3VA1163-3EF32-0JA0 SENTRON molded case circuit breaker, 63 A rated at 40 °C, 3-pole, TM240 thermal-magnetic release, breaking capacity 75.6 kA at 240 V.
