Circuit Breakers

The 4120-G214-J3M1-C4S0ZN-3A circuit breaker is an electro-mechanical device which is designed to provide protection against over-currents in an electrical system. It works by interrupting the current flow through the circuit when the current reaches an unsafe level. The circuit breaker is typically installed in the main electrical panel in residential or commercial properties, and also in industrial settings.

Application Field

The 4120-G214-J3M1-C4S0ZN-3A circuit breaker is designed for use in industrial settings, such as machine shops and manufacturing plants, where it is used to protect the electrical system from over-currents. It is also suitable for use in residential and commercial settings, providing protection against electrical shock and overbulks in appliances or lights. The 4120-G214-J3M1-C4S0ZN-3A is also used in motor-control centers to protect the motor and other electrical components from overloads.

Working Principle

The 4120-G214-J3M1-C4S0ZN-3A circuit breaker works by using a bimetallic strip. This strip is heated up when an over-current flows through it. The strip bends as it is heated up, which in turn causes a set of electrical contacts to open, thus interrupting the current flow. The contacts can then be re-closed when the excessive current has been removed from the system. The circuit breaker also has a handle which can be used to manually open the contacts and reset the circuit breaker.

The 4120-G214-J3M1-C4S0ZN-3A circuit breaker can either be a single-pole or a three-pole breaker, depending on the application. In a single-pole breaker, the bimetallic strip is connected to only one of the electrical lines, whereas in a three-pole breaker, the bimetallic strip is connected to three electrical lines, providing protection from over-currents in all three lines.

The 4120-G214-J3M1-C4S0ZN-3A circuit breaker is also equipped with an over-current warning system. This system can detect when the current flow through the breaker is about to reach an unsafe level and will warn the user before it is too late. This is to prevent the over-current from reaching a dangerous level before the circuit breaker trips.

The 4120-G214-J3M1-C4S0ZN-3A circuit breaker is designed to provide reliable protection against over-currents in an electrical system. It is constructed using high-quality materials and components to ensure a long life and safe operation. It is suitable for use in various applications, from residential and commercial to industrial, and can provide protection against current overloads and over-voltages.
