The 70 mm depth and 76.2 mm width fit the standard SENTRON 3VA panel footprint — same cutout and bus-bar spacing as the rest of the 3VA family — so it drops into an existing SENTRON-based distribution board without re-drilling the mounting plate or re-spacing the bus bars. At 55 °C it steps to 38.4 A, and at 70 °C it reaches 36 A, a 10 % reduction from the nameplate. The trip alarm switch signals a fault trip separately from the aux contacts, which is useful for remote annunciation in a PLC input. The auxiliary trip module is order code 3VA9608-0BB11, a separate line item if the factory-fitted block ever needs replacement.","metaTitle":"Siemens 3VA1140-4EF36-0BH0 SENTRON MCCB, 40 A, 3-Pole, 70 mm","metaDescription":"Siemens 3VA1140-4EF36-0BH0 SENTRON molded case circuit breaker, 40 A rated continuous current, 3-pole, TM240 release, 121 kA at 240 V.
