3900-P10-SI-6A Circuit Protection

Circuit Breakers

A circuit breaker is an important part of an electrical system that is designed to protect it from overloads. The 3900-P10-SI-6A circuit breaker is a type of circuit breaker that is commonly used in residential, commercial, and industrial installations. It is designed to protect the circuit and its components from overcurrents, short circuits, and other electrical hazards.

Application Field and Working Principle of 3900-P10-SI-6A Circuit Breaker

The 3900-P10-SI-6A circuit breaker is designed for use in residential, commercial, and industrial locations where overcurrent protection is needed. The breaker is designed to trip when the current in the system exceeds the rated value of the breaker. This helps to protect the electrical system from overloading and the potential of short circuits. The breaker can also be used as a safety device if the current reaches a hazardous level, as it will automatically trip and shut down the electrical system.

The 3900-P10-SI-6A breaker is rated for 16 A and is designed to operate at a voltage of 240V. It can be used to protect single-phase or three-phase circuits. The contact system in the breaker is made of a silver-nickel alloy that is plated with tin for corrosion resistance. The contacts are connected to a small plunger that is activated by the tripping mechanism when the rated current is exceeded. The plunger then separates the contacts to shut off the circuit.

The breaker has a thermal and magnetic trip unit that monitors the current passing through the circuit. If the current exceeds the maximum rating, the breaker will trip and shut off the power before any damage can occur. The thermal trip unit works by measuring the heat generated by the current in the circuit. If the temperature rises due to overload, it will trip the breaker, preventing further damage to the circuit. The magnetic trip unit is an electromechanical device that uses a small iron core to control the tripping mechanism. The small core is surrounded by a coil, which generates a magnetic field when current passes through it. When the current reaches a certain level, the magnetic field will be strong enough to cause the tripping mechanism to operate.

The 3900-P10-SI-6A circuit breaker is a reliable and cost effective way to protect electrical circuits from overloads and short circuits. It is easy to install and can be used to help protect both single-phase and three-phase circuits. The breaker is designed to work with modern electrical systems and can be used to protect systems from a wide range of hazardous conditions. It is an effective tool for protecting both residential and commercial electrical systems.
