That thermal stability matters when the breaker shares a crowded enclosure with other heat sources; you don't lose headroom the moment the panel warms up. At 240 V it handles 75.6 kA; at 415 V, 52.5 kA; at 440 V, 32 kA; and at 500 V or 690 V it still holds 11.9 kA. That's a strong SCCR for a 32 A frame — it gives you headroom for high-fault-capacity installations where the available short-circuit current at the panelboard is substantial. That's a common requirement for motor feeder protection where you want the breaker to drop out on loss of control power, preventing an automatic restart. The UVR is built into the basic switch (order code 3VA11323EF320AA0). Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a compact footprint for a 32 A MCCB with this interrupting capacity. The 3-pole width of 76.2 mm (3 inches) is standard for a 160 A frame MCCB, so it occupies one full module position in most panelboard layouts. Depth of 70 mm (2.76 in) keeps the breaker within typical enclosure depth limits, leaving room for wiring gutters and busbar connections behind the mounting plate. In a multi-breaker panel that figure adds up, so account for it in your thermal calculation — especially if the enclosure is sealed or has limited ventilation.","metaTitle":"Siemens 3VA1132-3EF32-0CA0 SENTRON MCCB, 32 A, 75.6 kA at 24","metaDescription":"Siemens SENTRON 3VA1132-3EF32-0CA0 molded case circuit breaker, 3-pole, 32 A rated at 40 °C, 75.6 kA interrupting at 240 V.
