CR16-52-20.0A-38963-20-V

Circuit breakers are electrical devices that protect electrical systems from short circuits and overloads. The CR16-52-20.0A-38963-20-V is a product in this category. Understanding its application field and working principle is an essential requirement for those involved in its installation and use.The application field of the CR16-52-20.0A-38963-20-V circuit breaker covers a broad spectrum of applications in residential, commercial and industrial environments. It is suitable for use as a branch breaker in larger systems, as well as for single pole switching circuits. Its design allows for installation into either a main lug panel or main breaker panel, making it a versatile and cost-effective choice for a variety of applications.The working principle of the CR16-52-20.0A-38963-20-V circuit breaker is based on the physics of electricity and heat dissipation. The breaker is designed with a thermal-magnetic trip unit that contains two temperature sensitive mechanisms: a bimetallic element and a thermal cut-off fuse. The bimetallic element responds to the heat caused by an overload or short circuit and triggers the thermal-magnetic trip unit. This, in turn, trips the breaker and disconnects the power to the circuit. The thermal cut-off fuse serves as a back-up trigger, should the bimetallic element fail and not trip the breaker. In order to reset the breaker, the cause of the overload must be eliminated and the breaker must be manually reset.The CR16-52-20.0A-38963-20-V circuit breaker is an essential component for any system that requires reliable protection against overloads and short circuits. Its combination of features makes it an optimal choice for a variety of applications in residential, commercial and industrial environments. With an understanding of its application field and working principle, it is possible to take full advantage of the protection provided by the CR16-52-20.0A-38963-20-V circuit breaker.
