Often called a manual starter, motor-automatic, or engine protection circuit breaker, the NS2-25 0.63-1A is fundamentally an automatic circuit breaker designed with motor control in mind. It provides both engine protection and start/stop functionality. Featuring a magnetic trip unit for short-circuit protection, this motor starter is calibrated to tolerate up to 18 times the nominal current, preventing nuisance tripping during motor startup. This makes it ideal for reliable motor control applications.

Often called a manual starter, motor starter, or motor protection circuit breaker, the NS2-25 0.4-0.63A combines the functionality of a standard circuit breaker with motor control capabilities. It protects your motor from short circuits with a magnetic trip unit, specifically calibrated to allow for the higher inrush currents experienced during motor startup – up to 18 times the nominal current – preventing nuisance tripping. This provides reliable motor starting and stopping with integrated control.

Often called a manual starter, motor starter, or engine protection circuit breaker, the NS2-25 0.25-0.4A is fundamentally an automatic circuit breaker designed with motor protection in mind. It provides both switching and stopping capabilities, along with integrated controls, qualifying it as a starter. Featuring a magnetic trip unit for short-circuit protection, this motor starter distinguishes itself from standard breakers with a trip setting of 18 times the nominal current, preventing nuisance tripping during motor startup.

Often called a manual starter, motor-automatic, or engine protection circuit breaker, the NS2-25 0.16-0.25A is fundamentally an automatic trip switch. However, it goes beyond basic protection, offering motor start/stop functionality and integrated controls characteristic of a dedicated motor starter. Featuring a magnetic trip unit for short-circuit protection, this motor-automatic is calibrated to tolerate up to 18 times the rated current, preventing nuisance tripping during motor startup.

Often called a manual starter, motor starter, or engine protection circuit breaker, the NS2-25 0.1-0.16A is fundamentally an automatic circuit breaker. However, it's specifically designed to protect electric motors, offering both start/stop functionality and integrated controls. A magnetic trip unit safeguards against short-circuit currents, and unlike standard breakers, its trip curve is set to 18x the nominal current to prevent nuisance tripping during motor startup.

This modular contactor with manual operation is designed for both manual and remote control of resistive loads like electric heaters, household appliances, and other low-inductive equipment. Crucially, contactors do *not* provide protective functions. Always use them in conjunction with circuit breakers and other devices offering overload and short-circuit protection for a safe and reliable electrical system.
