Two poles let it switch both line and neutral on a 277 VAC single-phase circuit, or both legs of a 110 VDC supply. ## Panel integration Two-pole width is 36 mm — two module spaces. Wire termination is via tunnel terminals; strip length and torque follow the ABB S800 series installation guide. No auxiliary contact slot on this base unit, but the S800 range accepts plug-in accessories for alarm or shunt-trip if the application needs remote signaling.","metaTitle":"S801UE-K20 MCB, 2-Pole, Trip Curve B, 6 A, 277 VAC, DIN Rail","metaDescription":"S801UE-K20 miniature circuit breaker, 2-pole, Trip Curve B, 6 A, 277 VAC/110 VDC, 6 kA interrupting.
