Circuit breakers are rule-based devices that sense potential overloading and prevent circuits or systems from being damaged by overloading or short circuiting. The 219-3-6391-006 is a three-pole, interrupting-only circuit breaker designed for protection of low-voltage circuits. It is suitable for use in Branch circuits, Junction boxes, and Panelboards.

This circuit breaker offers two features that are beneficial in hazardous locations. First, it has integral ground fault (EGF) protection, which helps protect personnel and equipment in hazardous locations with the possibility of shock hazards. Second, it contains a trip indicator, which alerts users to the open position of the breaker before applying line voltage.

The 219-3-6391-006 is constructed from durable materials, including a plastic cover plate that has a NEMA 4X rating against water, oil, and temperature. The breakers also offer a wide range of protective elements, such as overcurrent trip, short-circuit trip, and overload trips. Additionally, these breakers feature a reset button, which allows the circuit breaker to be reset after tripping.

The working principle of the 219-3-6391-006 is based on electromagnetism: the electromagnet in the breaker operates on the principle of magnetization and demagnetization. When the current in a circuit exceeds the specified threshold, the electromagnet rapidly magnetizes, pulling the breaker’s operating arm closed, and opening the electrical circuits. When the current in the circuit returns to its normal level, the electromagnet gradually demagnetizes, releasing the spring-loaded arm, and allowing the circuit to resume regular operation.

The 219-3-6391-006 is a versatile circuit breaker that is suitable for use in a variety of applications, including residential, commercial, and industrial power systems. It can be used to protect against overloads, short circuits, and ground faults, as well as protect against other hazardous conditions.

The 219-3-6391-006 offers superior protection and is an ideal choice for applications that require reliable circuit protection. It is designed to be easy to install and operate, and it can be safely configured to meet a variety of needs. Its durability and versatility make it a great choice for residential, commercial, and industrial applications.
