Circuit breakers are devices that are designed to automatically cut off power to a malfunctioning circuit or system, preventing serious damage to the system and potentially preventing a dangerous electrical shock hazard to those operating the system. The 4400.0065 model circuit breaker is a common professional-grade breaker used for commercial and industrial applications. This article will discuss the application field and working principle of the 4400.0065 circuit breaker.

The 4400.0065 model circuit breaker is designed for use with 120/240 volt, 3-wire, single and three-phase alternating current (AC) supply systems. It is constructed of high-impact abrasion-resistant thermoplastic and is UL 489 listed for standard duty applications. It has a maximum interrupting capacity of 10,000 amps symmetrical at 150 volts, and is rated for UL 2,000 amperes at 240 volts AC. The 4400.0065 is available in a variety of amperages, as well as a variety of poles, such as 1-pole, 2-pole, 3-pole, or 4-pole configurations. As a result, this is a versatile circuit breaker that can cover a wide range of commercial and industrial applications.

The 4400.0065 circuit breaker works by measuring the current flow to a circuit and cutting off the power to the circuit when the current exceeds a predetermined level (the maximum capacity of the breaker or the trip rating). It does this by using a bimetallic strip, which is made up of two different metals that have different thermal expansion coefficients. When current flows through the circuit, the metals in the bimetallic strip expand at different rates, causing the strip to bend and activate the trip mechanism, which cuts off the power. This ensures that the system will not be damaged if the current exceeds the trip rating of the device.

The 4400.0065 circuit breaker can be used in a variety of applications, such as residential, commercial, and industrial. It is suitable for use in air conditioners, alarm systems, pool pumps, heat pumps, garbage disposals, power tools, and other applications that require a circuit breaker. It is also suitable for use in high-demand industrial environments, such as machine tools, production lines, and manufacturing plants. The 4400.0065 also has safety features, such as a ground-fault circuit interrupter (GFCI) for added safety protection against shock hazards.

In conclusion, the 4400.0065 circuit breaker is a versatile and dependable professional-grade breaker that is designed for use in both commercial and industrial applications. It measures the amount of current flow to a circuit and cuts off the power when the current exceeds the trip rating. It is suitable for use in residential, commercial, and industrial applications, such as in air conditioners, alarm systems, pool pumps, and other high-demand applications. The 4400.0065 is also equipped with safety features, such as a GFCI, to provide additional protection against hazardous electrical shock.
