Industrial DUK222790 Magnetic Contactor 3 Pole

The Duke DUK222790 Magnetic Contactor is an industrial 3-pole device designed to switch three-phase loads in control panels and starter circuits. Rated at 240 VAC and 30 A, it supports both 50 Hz and 60 Hz power systems, enabling use in regions with either frequency without needing different units. The three poles allow simultaneous switching of all three phases, making it suitable for controlling moderate-sized three-phase motors, conveyors, pumps, fans, and other inductive loads in commercial and light industrial applications. As a magnetic contactor, it employs an electromagnet to operate the contacts, providing a compact, dependable solution for on/off control of line-voltage equipment. The DUK222790 model is part of Duke’s line of industrial contactors, which are commonly integrated into control panels and motor control circuits where a robust switching device is required. This description reflects only the stated specifications: 3 poles, 240 V, 30 A, with 50/60 Hz compatibility. For system designers and panel builders, this unit offers a straightforward means to implement remote or automated control of three-phase equipment using a single three-pole contactor.
