The 800 V rated insulation voltage (Ui) tells you the breaker is designed for 480/277 V and 600 V systems with margin, but the 690 V breaking capacity is only 17 kA — so if you are protecting a 690 V motor drive, confirm the SCCR of the downstream equipment is coordinated with that figure. ## Temperature derating — don't ignore it At 55 °C it drops to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A. The thermal trip element responds to ambient temperature; packing the panel full of breakers without ventilation will nuisance-trip the 50 A setting long before the load hits 50 A. Four-pole at 101.6 mm wide — that is a standard 4-inch footprint, so it fits a typical 4-pole MCCB slot in a Siemens SENTRON panelboard or a DIN-rail adapter.","metaTitle":"Siemens 3VA1110-5FE46-0AA0 SENTRON MCCB, 50 A, 4-Pole, TM220","metaDescription":"Siemens 3VA1110-5FE46-0AA0 SENTRON molded case circuit breaker, 50 A rated, 4-pole, TM220 thermal-magnetic trip, 187 kA at 240 V.
