The auxiliary contacts report breaker position back to the PLC or status panel without a separate contactor block. No communication module or ground-fault monitoring on this order code. If you need Modbus or RCM, step to the 3VA2 communication-capable frame. The 3VA1 platform here is a pure electromechanical MCCB with a trip-indicator flag. The 3-pole footprint is standard for the 3VA1 frame — drops into the same cutout as the 3VA1 160 A frame, so a panel laid out for a larger rating accepts this 50 A unit without rework.","metaTitle":"Siemens 3VA1050-3ED36-0CH0 SENTRON MCCB, 50 A, 75.6 kA","metaDescription":"Siemens SENTRON 3VA1050-3ED36-0CH0 molded case circuit breaker, 3-pole, 50 A at 40 °C, breaking capacity 75.6 kA at 240 V AC.
