Those numbers cover the full range of common industrial distribution voltages — 240 V single-phase, 415/440 V three-phase, and 690 V for heavy plant. ## Thermal derating — what the 50 A rating actually means The 50 A rating holds from 40 °C through 50 °C, then begins to taper: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. Plan your load margin accordingly; the breaker will not trip early, but it will run warmer. ## Overcurrent release and auxiliary contacts That is a standard choice for general-purpose feeder protection.","metaTitle":"Siemens 3VA1150-4EF36-0DH0 SENTRON MCCB, 50 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1150-4EF36-0DH0 molded case circuit breaker, 50 A rated, 3-pole, line protection.
