The interrupting ratings are the real selector: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. These numbers govern whether the breaker holds under a bolted fault at the available fault current on that bus. The TM210 trip unit is a fixed thermal-magnetic design — no interchangeable electronic trip module, no ground-fault or communication function. For a BOM freeze, the key fit check is whether the 50 A continuous rating and the interrupting capacity at your system voltage match the load and the available fault current on the distribution board. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — the width is a standard 3-pole MCCB footprint for the 3VA frame size.","metaTitle":"Siemens 3VA1050-4ED36-0BC0 SENTRON MCCB, 50 A, 3-Pole, 121 k","metaDescription":"Siemens 3VA1050-4ED36-0BC0 SENTRON 3-pole molded case circuit breaker, 50 A rated continuous current, TM210 trip unit, interrupting ratings up to 121 kA at 240 V.

The fit is mechanical; the difference is in the trip unit and ratings — the 3VA1050-4ED36-0BC0 carries a 50 A TM210 thermal-magnetic release, while the 3VA1010-2ED36-0AC0 is a lower-current variant. No rewiring is needed for the drop-in, but the continuous current rating and interrupting capacity must match the circuit design."},{"question":"What compliance documentation does Siemens provide for this MCCB?","answer":"As a SENTRON 3VA series product, the breaker carries the standard Siemens compliance documentation including CE marking, RoHS and REACH declarations, and UL/IEC certifications for the series.
