Above that, it derates: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, 36 A at 70 °C. ## Panel fit — dimensions and mounting Width 76.2 mm, height 130 mm, depth 70 mm. The IP40 front rating means the breaker face is protected against solid objects >1 mm, but the body expects enclosure protection for the terminals.","metaTitle":"Siemens 3VA1140-4EF36-0JH0 SENTRON MCCB, 40 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1140-4EF36-0JH0 molded case circuit breaker, 40 A rated, 3-pole, 121 kA breaking at 240 V.

Verify the mounting hole pattern and busbar spacing from the respective dimensional drawings — the 3VA1140-4EF36-0JH0 has a 76.2 mm width and 130 mm height, which is standard for the 3VA platform, but the lug kit and terminal layout may differ.
