Breaking capacity is rated at 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. At 40 °C through 50 °C it carries the full 50 A; derating begins at 55 °C (48 A), dropping to 45 A at 70 °C. Dimensions: 130 mm height, 101.6 mm width, 70 mm depth. Latching endurance rated at 15 000 cycles. The TM210 release means trip settings are factory-fixed; no field-adjustable thermal or magnetic dials. If your BOM calls for electronic adjustability or zone-selective interlocking, this is not the variant. At 690 V the capacity drops to 7.5 kA — verify available fault current if this breaker lands on a 690 V bus. The 75.6 kA at 240 V covers high-fault North American 240/120 V services. The 4-pole design with neutral protection absent (no N-conductor protection) means the fourth pole is a switched neutral, not a protected pole. If your application requires neutral protection, this unit does not provide it. The 101.6 mm width (4-pole) occupies four 25 mm module spaces — plan gland-plate fill accordingly. The two HQ auxiliary switches are wired separately; verify the free-wheeling diode polarity on the shunt trip coil (STL) before energizing. No communication module or voltage trigger tap is present — this is a standalone breaker, not a power-monitoring node.","metaTitle":"Siemens 3VA1050-3ED42-0HC0 SENTRON MCCB, 50 A, 4-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1050-3ED42-0HC0 molded case circuit breaker, 50 A rated continuous current, 4-pole, breaking capacity 75.6 kA at 240 V.
