Three poles, rated insulation voltage 800 V, and a 3-pole footprint that fits standard SENTRON panel mounting. The 75.6 kA at 240 V is the highest interrupting rating on this breaker; at 415 V it drops to 52.5 kA, at 440 V to 32 kA, and at 500 V / 690 V to 7.5 kA. That steep derating above 480 V means this frame is really at home on 240 V or 400 V-class systems where fault currents are high — not on 690 V motor circuits where available fault is modest. Compared to the 3VA1010-3ED36-0AA0 (a 100 A frame in the same SENTRON family), the 3VA1040-3ED32-0JC0 shares the same 3-pole form factor and shunt trip option but is sized for a 40 A load rather than 100 A. The panel cutout and bus connection pattern are identical — swap the breaker, not the panel layout. ## Panel integration — dimensions and mounting","metaTitle":"Siemens 3VA1040-3ED32-0JC0 SENTRON MCCB, 40A 3-Pole, 75.6kA@","metaDescription":"Siemens SENTRON 3VA1040-3ED32-0JC0 molded case circuit breaker, 40A rated at 40°C, 3-pole, 75.6kA breaking at 240V.
