983-21 ES

The motor protection switch 983-21 ES is a versatile device used mainly for switched continuous current and voltage protection of motors and other types of loads. It provides a greater degree of protection than other types of electricswitch, while maintaining an alarm system for potentially defective electrical equipment. In addition, it is able to detect sudden changes in line voltage and current, which could potentially cause electrical damage.

The application field of this switch is mainly in industrial, commercial and residential applications. It can be used to protect motors of all sizes, from small fans to large industrial machinery. It is also suitable for the protection of heater elements, transformers, generators, lighting systems and other types of electrical loads.

The working principle of the 983-21 ES motor protection switch involves monitoring the voltage and current of the system. When the detected voltage or current is outside of the acceptable range, the switch will activate and shut off the power supply to the motor. This provides both protection for the motor and an alarm for any potential problems. Furthermore, it is possible to configure the switch to monitor and protect against low or high temperatures, phase imbalance and other potential hazards.

The 983-21 ES motor protection switch is a reliable solution that can help to protect valuable equipment from potential electrical damage. It is also highly configurable to provide an individualized level of protection, and its integrated alarm system ensures that any potential problems are quickly and effectively dealt with.
