That covers most industrial service entrances and downstream feeder panels; the 690 V figure matters for 600 V class installations where fault current can exceed 10 kA. Rated insulation voltage is 800 V, so the breaker is suitable for 480/277 V and 600/347 V systems with headroom. Power loss at rated load is 17.1 W maximum — account for that in a sealed, non-ventilated enclosure when stacking multiple breakers. ## Built-in Undervoltage Release and Auxiliary Switch Configuration The 76.2 mm width (3 inches) is the standard 3-pole MCCB envelope for this class — it fits existing SENTRON 3VA panel cutouts and busbar risers without adapter plates. ## Operating Environment and Lifecycle The trip indicator is present, so a visual flag confirms the breaker tripped on fault versus being manually switched off.","metaTitle":"Siemens 3VA1150-3EF36-0BH0 SENTRON MCCB, 50 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1150-3EF36-0BH0 molded case circuit breaker, 50 A rated at 40 °C, 3-pole, 75.6 kA breaking at 240 V.
