Circuit breakers are devices that are used to protect electrical circuits in the event of an overload, short circuit, or other fault. A circuit breaker is an automatic switch which will disconnect the circuit from the power supply when the current flowing through it exceeds a preset limit. This limit is determined by the rating of the breaker, which is set according to the fuse rating of the circuit it is protecting. The application field and working principle of the 299-3-1REC4-38508-1 Circuit Breaker are outlined below.

The 299-3-1REC4-38508-1 Circuit Breaker is a medium voltage air insulated circuit breaker that is designed to protect against overloads and short circuits in electrical systems up to 38 kV. It is suitable for applications in industrial and commercial electrical systems, as well as power transmission lines. The breaker is also capable of making and breaking safely under load and carrying rated currents up to 1250 A.

The 299-3-1REC4-38508-1 Circuit Breaker is operated through an electromechanical mechanism which is activated when an overload or short circuit occurs. When this occurs, an electric current passes through a solenoid, which is then used to open or close the breaker mechanism. This is done by a mechanical linkage which is connected to the solenoid. The mechanical linkage in turn moves several cam plates which cause the contacts of the breaker to open or close.

The 299-3-1REC4-38508-1 Circuit Breaker also features a safety trigger device. When the current that is flowing through the breaker exceeds the preset limit, the safety trigger is activated, which triggers a solenoid that causes the breaker to open. This feature helps to prevent any further damage to the circuit or to the breaker itself.

This Circuit Breaker also features a design of three poles and is explosion proof. It is equipped with a PU insulation which makes it suitable for outdoor and wet environments and it is UL listed, making it suitable for industrial and commercial applications.

The 299-3-1REC4-38508-1 Circuit Breaker is designed to protect against overloads, short circuits, or other electrical faults in industrial and commercial electrical systems. It features an electromagnetic mechanism, a safety trigger device, and is explosion proof for added safety. The breaker is also UL listed and compliant with national safety standards, making it a safe and reliable choice for industrial and commercial applications.
