Interrupting capacity is 52.5 kA at 240 V, dropping to 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500 V and 690 V — that 7.5 kA floor at 690 V tells you this is a 240/415 V distribution breaker, not a 690 V motor-circuit device. ## What the auxiliary configuration means for panel integration No undervoltage release fitted, no ground-fault monitoring module, no communication function — this is a plain line-protection MCCB with the basic remote-control options. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — standard 3-pole MCCB footprint for a 50 A frame, fits most distribution panelboards without a width surprise. ## How it compares to the 100 A frame sibling The closest functional sibling in the same SENTRON 3VA family is the 3VA1110-5ED36-0AC0, which is a 100 A frame on the same 3-pole platform — same 70 mm depth, same auxiliary switch options, but physically wider and heavier to handle the higher continuous current. If your BOM calls for 50 A line protection with shunt trip and alarm contacts, this 3VA1050-2ED36-0HH0 is the correct frame — the 100 A sibling would work electrically but overshoots the ampacity and takes more panel width.","metaTitle":"Siemens 3VA1050-2ED36-0HH0 SENTRON MCCB, 50 A, 52.5 kA at 24","metaDescription":"Siemens SENTRON 3VA1050-2ED36-0HH0 molded case circuit breaker, 3-pole, 50 A rated at 40 °C, 52.5 kA interrupting at 240 V.
