The DILER-31 is a low-voltage power contactor made by Eaton, a global industrial technology company. It is rated for 440V, 60Hz and 400V, 50Hz, and is ideally suited to applications requiring up to 33.5HP at 440V, 60Hz, and up to 28HP at 400V, 50Hz. The DILER-31 is suitable for both motor control and power switching applications, and is suitable for use with both conventional and solid-state overload relays. This power contactor also features a versatile modular design, allowing multiple contactors to be easily assembled into acontact block. The contact block is constructed of die-cast aluminum, making it highly resistant to shock, vibration and temperature changes, and ensuring superior performance in even the harshest operating environments.
