This MCCB delivers 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — numbers that put it in the high-interrupting class for industrial distribution. At 500 V and 690 V it still holds 17 kA, which covers most motor-circuit fault levels in 480/600 V class panels. The 40 A rating holds flat from 40 °C to 50 °C, then derates gradually: 39 A at 55–60 °C, 38 A at 65 °C, and 37 A at 70 °C. In a sealed panel with multiple breakers ganged together, that derating curve is what you use for the fill-factor calculation — the full 40 A only applies if ambient inside the enclosure stays under 50 °C. Front IP40 protects against tools and wires, not hose-down; mount it in a clean indoor MCC or panelboard, not a washdown zone. The 3VA series succeeded the 3VL family and is the standard MCCB offering from Siemens for panelboard and distribution applications. ## Dimensions and physical fit The breaker measures 130 mm high, 76.2 mm wide (3 inches — standard MCCB footprint for 3-pole 40 A frame), and 70 mm deep. That 70 mm depth is shallower than many 40 A MCCBs in the 3VA family, which helps when the gland plate or backplane clearance is tight. The width matches the 3-pole cutout in most Siemens panelboard interiors; no adapter plate needed.","metaTitle":"Siemens 3VA1140-6EE36-0AA0 SENTRON MCCB, 40 A, 3-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1140-6EE36-0AA0 molded case circuit breaker, 40 A, 3-pole, TM220 release.
