That thermal continuity means you can mount it in a warm cabinet without stepping up a frame size. The TM210 thermal-magnetic trip unit handles overload and short-circuit response in one package; no separate ground-fault module here. At 240 V it interrupts 75.6 kA; at 415 V that drops to 52.5 kA, and at 690 V it's still 7.5 kA. For a 40 A frame those are high-interrupt values — you can coordinate downstream of a larger upstream breaker without worrying about cascading failure during a bolted fault. That gives you a remote status signal for both the breaker position and the trip event — useful for PLC-based monitoring or for triggering an alarm on a critical feeder. ## Panel integration and physical fit The 3VA1040-3ED32-0AH0 occupies a 76.2 mm wide footprint on the DIN rail, 130 mm tall, 70 mm deep. Three-pole construction, so it fits standard 3-phase distribution sections.","metaTitle":"Siemens 3VA1040-3ED32-0AH0 SENTRON MCCB, 40 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1040-3ED32-0AH0 molded case circuit breaker, 40 A rated, 3-pole, TM210 trip unit, 75.6 kA breaking capacity at 240 VAC.
