Circuit breakers are electric switches used for the protection of electrical circuits. Designed to detect short circuits or overloads on the electrical system, they break the circuit or disconnect it by opening or clsoing the relevant circuit breaker contacts. The 3900-P10-SI-0.5A circuit breaker is a mid-range breaker for use in inverter and drive applications, and this article examines its application field and working principle.
Application Field
The 3900-P10-SI-0.5A circuit breaker can be used in a range of electrical systems, such as electrical circuit power supply systems, frequency converters, rectifiers, UPS and control systems. It is used to protect motors, electric tools, and other equipment that may overload the system and cause damage.
Working Principle
The 3900-P10-SI-0.5A circuit breaker is designed to detect when the current flowing through it exceeds a specified limit. It will then open the circuit, temporarily disconnecting the power source from whatever device the circuit it is connected to and preventing it from overloading. This type of circuit breaker also features a manual reset feature, which allows the circuit to be reset manually after an overload event.
The 3900-P10-SI-0.5A circuit breaker is designed to provide protection for a wide variety of applications, including machinery, motor controllers, inverters, and rectifiers. It has a short circuit current trip rating up to 0.5A, and can detect and break off any overload in the current flowing through it. It is designed to handle voltage surges up to 690V, and is capable of resisting the thermal and electromagnetic influences from the device it is connected to.
In addition to its overload protection feature, the 3900-P10-SI-0.5A circuit breaker also features a variety of other features that help protect the electrical system. It includes a built-in selftest feature to detect and test any faults in the system. It also comes with an audible alarm to alert the user if there is a fault in the system. This feature helps to identify any faults quickly and minimize downtime.
The 3900-P10-SI-0.5A circuit breaker is a versatile and reliable circuit breaker. It provides adequate protection against overloads and short circuits, and its automatic reset feature ensures that the power can be restored quickly after an overloading event. Combined with its other features, such as selftest and audible alarm, this circuit breaker is an ideal choice for a range of applications.
