Details:

It operates by utilizing the motors current to engage and disengage starting winding during startup. Key specifications: voltage ratings: the standard relays are rated at 10 amps for 120-volt systems and 5 240-volt. Application considerations: when selecting the KD138A relay for a specific application, its essential to consider motors start winding current, voltage , and frequency. Mounting orientation: for optimal performance, the relay should be vertically mounted.

Ensuring that the relays pickup and dropout ratings with motors specifications will promote optimal performance longevity. Current ratings: standard operating ratings are available from 1.0 to 20.0 amps, with specific model's offering precise pickup and dropout current settings match various motor requirements. All movable parts are fully enclosed, and a double pair of fine silver contacts provide two breaks in series, contributing to the devices long operational life. The GE Klixon KD138A relay is a current-type motor starting designed for single-phase ac hermetic refrigeration motors, as well split-phase and capacitor-start motors.

This orientation ensures that gravity aids in the reliable dropout of relay when motor reaches operational speed. Construction details: the relay comprises a solenoid coil, sliding steel armature centered around nylon guide bushing and brass pin, bridging-type contact arm actuated by. For comprehensive installation guidelines and detailed technical data, referring to the manufacturers data sheet is recommended.
