Often called a manual starter, motor-automatic, or engine protection circuit breaker, the NQ3-5.5P is fundamentally an automatic switch designed to safeguard motors. It provides both motor protection and control, offering start/stop functionality. Equipped with a magnetic trip unit, it protects against short-circuit currents. Unlike standard breakers, its trip unit is set to 18x the nominal current, preventing nuisance tripping during motor startup.
NQ3-5,5P 1,6A 220B is a versatile device functioning as both a circuit breaker and a motor starter, often referred to as a motor-automatic. Designed for 220V applications, this unit provides comprehensive protection for motors up to 1.6A, including overload and short-circuit protection via a magnetic trip mechanism. Its integrated control functions allow for convenient starting and stopping, making it ideal for a wide range of motor control applications.
