Electromagnetic switch JD3 — Model KJD11A Key benefits - Protects motors from damage by providing undervoltage and overload protection. - Improves safety with an integrated emergency stop function that quickly interrupts motor operation. - Reliable operation in wet or damp environments thanks to waterproof construction. - Simple, focused protection and control for motor applications where safety and uptime matter. Core features - Function: Motor control with undervoltage protection, overload protection, and emergency stop capability. - Model: KJD11A (JD3 electromagnetic switch). - Environmental: Waterproof housing to maintain reliability in moist or outdoor locations. - Performance: Designed to detect undervoltage and overload conditions and act to prevent motor damage and unsafe operation. How this solves common problems - Prevents motor burnout and costly repairs by interrupting power during overload conditions. - Avoids erratic motor behavior and potential equipment damage during low-voltage events by isolating the motor until normal voltage returns. - Provides immediate shutdown via the emergency stop function to reduce injury risk and stop hazardous operation. - Maintains reliable operation in wet environments, reducing downtime from moisture-related failures. Typical applications - Water pumps and irrigation systems: protects pump motors from overloads and low-voltage conditions and withstands wet locations. - Industrial conveyors and material handling: provides motor protection and an emergency stop option for safer operation on the line. - HVAC and ventilation motors: adds undervoltage and overload protection and ensures safe shutdown when needed. Compatibility and installation notes - Intended for motor control circuits using an electromagnetic switch of model KJD11A (JD3). - Check the manufacturer's datasheet for electrical ratings, mounting dimensions, and wiring details to confirm compatibility with your specific motor and control system.
