SPX understands that true motor control begins with safety. Magnetic Starters with Overload， It is based on this concept that an integrated security control terminal is designed. In the pulsation of industrial production, electric motors are the eternal driving heart. And every abnormal overload, every unexpected blockage, may cause irreversible damage to this heart. It is not only about starting and stopping the motor, but also a "monitor" that monitors the operation status of the motor 24/7. It takes decisive action in the first time a fault occurs, minimizing losses.
The deep integration of electromagnetic contactors and overload relays (thermal magnetic or electronic) in both physical and electrical aspects eliminates complex wiring and compatibility issues between discrete components.
The protection signal is directly embedded in the control circuit, with faster response speed and much higher stability than external wiring schemes, reducing protection failure caused by loose wiring from the source.
Accurately simulate the heating curve of the motor, the larger the overload current, the shorter the action time, effectively preventing the motor insulation from overheating and aging.
Magnetic Starters with Overload monitors the three-phase current in real-time and quickly disconnects the power supply when any phase is missing, avoiding motor burnout caused by single-phase operation.
Provide quick trip protection in case of severe jamming during motor start-up or operation.
This product is a standard and necessary configuration for motor control in the following scenarios:
Prevent overload caused by load changes or valve failures for water supply pumps, sewage pumps, cooling tower fans, and HVAC system fans.
Conveyor belts, elevators, and spiral feeders are used to avoid motor stalling caused by material blockage.
Compressors, crushers, mixers, injection molding machines, protect the safety of motors when processing hard objects or under abnormal working conditions.
Use Magnetic Starters with Overload as the first and most important safety line of defense for any critical driving point that may cause the entire line to shut down due to motor failure.
Why choose our product?
Our Magnetic Starters with Overload were born from our profound understanding of motor control and protection systems. In our modern factory equipped with first-class laboratories and full process testing facilities, each starter is not only assembled, but also the system's compatibility calibration:
We have always ensured that the protection characteristics of the overload relay are highly consistent with the thermal characteristic curve of the target motor, achieving neither excessive nor insufficient protection.
Magnetic Starters with Overload require mechanical and electrical life testing that far exceeds industry standards, simulating the most rigorous on-site start stop and load conditions, so you only need to use our products with confidence.
From the incoming inspection of core components to the final testing of finished products, the entire process data can be traced, making accidents traceable and providing you with high-quality products
