Sylvania T77U021 Contactor

Sylvania T77U021 is a 30 Amp, three-pole contactor (NEMA Size 1) with a 110/120 VAC control coil, engineered for reliable motor switching in compact control panels and robust enough for the demands of commercial and light-industrial equipment. The three main power contacts are designed to carry up to 30 A, supporting typical loads such as compressors, pumps, and fans in standard control circuits, while its compact form factor and standardized mounting holes simplify installation in industry-standard panels and enclosures. As part of the Joslyn Clark family of motor-control devices, the T77U021 inherits decades of industrial design, offering durable switching performance in environments that demand dependable operation of medium-power loads. With a North American-friendly NEMA Size 1 footprint and a straightforward coil-to-control interface, the T77U021 delivers plug-and-play compatibility for common 120 VAC control circuits and widely used enclosure configurations, enabling reliable operation in equipment commonly controlled by contactors in commercial and light-industrial settings.
