295-1111-29129-1 Circuit Protection

Circuit breakers are designed to protect electrical systems, wiring, and components from damage resulting from short circuits, overloads, or faults. The 295-1111-29129-1 circuit breaker is a type of air-blast circuit breaker and is used in high voltage applications of up to 59 kV. It is used for power distribution and motor control in power systems, as well as for general switching applications.

Circuit breakers are made up of several components, including contacts, a trip unit, a latch mechanism, and an arc extinguishing chamber. The contacts provide a path for current to flow and are opened or closed by the trip unit to control current flow. The trip unit is responsible for sensing an overload or short circuit condition, and is also responsible for resetting the breaker once the fault is cleared. The latch mechanism holds the contacts open during an overcurrent condition, ensuring that the breaker remains open until the fault is cleared. The arc extinguishing chamber is used to contain and suppress the high-intensity arcs produced when the contacts open.

The 295-1111-29129-1 circuit breaker has a simple yet effective design which makes it reliable and easy to maintain. It has a two-stage current sensing system that is capable of tripping the breaker more efficiently at both high and low currents. The extra features provided by this circuit breaker, such as simple arc suppression and improved insulation, add to its reliability. The breaker has a Self-Running Dry Contactor which simplifies the charging of the control and trip circuits. It also has integrated voltage and current sensors that provide added protection and accurate trip characteristics. The breaker also features fast-responding contacts which can open in less than one millisecond to minimize fault damage.

The 295-1111-29129-1 circuit breaker is typically used in medium voltage power systems. It is suitable for generator, motor, and transformer protection, as well as for metal-clad switchgear applications. It is often used in medium voltage distribution systems, as well as for breaker/contactor applications in power distribution schemes. The breaker is also capable of providing reliable switching operations and is suitable for use in both indoor and outdoor applications.

In summary, the 295-1111-29129-1 circuit breaker is a reliable and durable breaker designed for high voltage applications. It has features that provide dependable overload protection and fast switching operation, allowing it to be used in both indoor and outdoor power systems. Its simple yet effective design ensures that it is easy to install and maintain. With its reliable protection, long life, and fast response time, the breaker is an ideal choice for both power and motor control applications.
