Breaking capacity is the headline number here: 75.6 kA at 240 V, 52.5 kA at 415 V, and still 11.9 kA at 690 V. For a panel OEM or site electrical engineer, that simplifies selectivity coordination and keeps the upstream transformer sizing honest. ## Undervoltage release and auxiliary release design The basic switch assembly is order code 3VA11323EF320AA0, so if you're panel-building and need the sub-assembly for a replacement, that's the part to cross-reference. No ground-fault monitoring, no communication function, no trip indicator — this is a straightforward thermal-magnetic line protection breaker (TM240 overcurrent release design). The undervoltage release is the only auxiliary, so if your BOM calls for shunt trip or GFCI, this isn't the variant. The 76.2 mm width (3 inches) is standard for a 3-pole MCCB in this frame size, so it fits existing SENTRON 3VA mounting bases without adapters. ## Thermal performance and power loss Maximum power loss is 13.1 W — that's the heat the breaker dissipates at full rated current. In a densely packed panel, that figure feeds the thermal budget for enclosure ventilation or derating of adjacent devices.","metaTitle":"Siemens 3VA1132-3EF32-0DA0 SENTRON MCCB, 32 A, 3-Pole, 75.6","metaDescription":"Siemens 3VA1132-3EF32-0DA0 SENTRON molded case circuit breaker, 32 A rated at 40 °C, 3-pole, 75.6 kA breaking capacity at 240 V.
