That's enough fault-clearing capacity to serve as a main breaker in a high-fault panel without cascading upstream. At 55 °C it drops to 38.4 A, at 60 °C to 37.6 A, at 65 °C to 36.8 A, and at 70 °C to 36 A. If your panel runs hot, size the load accordingly. The undervoltage release (UVR) is factory-fitted — part of the design, not an add-on. The integrated undervoltage release (3VA9608-0BB11) is wired separately from the main power path; confirm polarity and control voltage before energizing.","metaTitle":"Siemens 3VA1140-5EF36-0BA0 SENTRON MCCB, 40 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1140-5EF36-0BA0 molded case circuit breaker, 40 A rated, 3-pole, line protection. 187 kA at 240 V, 121 kA at 415 V.
