Overview
The Square D TeSys SK CA2SK20U7 is a compact control relay in the TeSys SK series, rated 10A at 690V AC with a 240V AC coil. The two normally open (2 NO) contacts provide switching capacity for control circuit logic in machine, panel, and automation applications. Screw clamp terminals ensure reliable conductor retention and easy wiring in the field. At 56 x 27 x 55.5 mm, the slim profile conserves panel space in dense control enclosure configurations. The 16/4.2 VA coil power draw is low enough to minimize transformer loading in multi-relay control systems.
