2907493

Circuit breakers are essential components within an electrical system. They present a reliable and cost-effective means of protecting people and assets from dangerous surges of electricity. Simply defined, circuit breakers are devices that are designed to open or close a circuit, or switch between the two. Commonly, these devices protect an electrical system from overcurrent or short circuit conditions. In other words, by tripping or breaking the circuit, the breaker helps to prevent damage to electrical components, potentially saving lives in the process.

Model 2907493 is a 3-pole, non-grounded, circuit breaker made by a well-known manufacturer of this type of equipment. The device is Certified Underwriters Laboratories (UL) Listed, which means it is compliant with industry safety standards recognized throughout North America. Furthermore, the 2907493 can withstand up to 10,000 AIC maximum and has a rated voltage of 480 V AC/250 V DC.The device meets Underwriters Laboratories (UL) 489B Standard, which is an important geographic indicator of electrical safety.

The 30A single-pole type of this breaker is rated for 30A, and is intended for use in commercial, industrial and marine applications. The device is designed to detect and protect against short-circuits and it can safely carry up to seven times of its rated current for short periods of time. The wide-ranging applications for this device include arc welding and machine tools, as well as industrial, commercial and residential uses. It is also suitable for motor loads, transformers, air conditioners and cooking equipment.

The working principle of this circuit breaker is the same for all types of ultraviolet and magnetic breaker models. The breaker works by detecting an increase in current flow and breaking the electrical circuit before it reaches a level where it may damage the equipment, or even cause death or injury to persons nearby. A current sensing bimetal element is used to detect the rising current level and actuate a moving mechanical contact, thus tripping the circuit breaker.

The breaker is also equipped with a thermal overload device which will sense the temperature of the conductor, and trip the circuit breaker if the thermal limit has been exceeded. This additional safety feature helps to provide better protection against equipment losses due to overloading. The 2907493 also features magnetic trip units, which work in combination with the current sensor to detect both low and high current conditions, further protecting malfunctioning equipment from causing further damage.

In summary, the 2907493 3-pole, non-grounded circuit breaker is one of the most reliable circuit protection devices on the market today. Weighing in at only 1.3lbs, this UL Listed breaker can be used in a variety of applications and is designed to be very reliable and cost effective. Its bimetal element, thermal overload protection and three-pole design makes it an ideal choice for protecting personnel and equipment from the risks of short-circuits, overloads and other damaging events.
