Contactors

Overview

Medray procures contactors for maintenance, replacement and project requirements. Provide the model or reference, quantity and operating conditions so the required configuration can be matched and sourced across available suppliers. A contactor uses an energized coil to open or close main power contacts, allowing a control circuit to operate a larger electrical load. Auxiliary contacts provide interlocking or status feedback. Select the utilization category and duty for the load, then match the coil supply, main pole arrangement, auxiliary contacts and terminal configuration. Motor switching and resistive-load current ratings have different operating contexts and must remain tied to the selected model. Technical details to confirm: Utilization category and load duty; Control-coil AC/DC voltage; Main poles and auxiliary contacts; Motor rating at supply voltage; Terminal and mounting arrangement.
