CARACT\u00c9RISTIQUES<\/span><\/strong><\/h2>\n
<\/div>\n
The versatility of normally closed DC contactors is reflected in their wide range of applications. One of the main uses is in safety protection systems. In emergency situations, such as equipment failure or dangerous situations, the ability to immediately cut off the power supply is crucial. Normally closed contactors are often integrated into emergency stop buttons, ensuring that the power supply can be disconnected quickly, thus preventing accidents and injuries.<\/div>\n
