Circuit breakers are special types of automated switches that are designed to protect an electrical circuit from damage due to overload or short circuit. They are made of two pieces of metal that snap-together when a certain level of current or voltage is passed through them, effectively stopping the flow of electricity. The APG2-9739-7 is an example of a circuit breaker used in many applications. This type of breaker has a two-pole configuration, meaning that two independent circuits share the same breaker, allowing for both protection and versatility in applications. The pole types available are SPDT (single-pole double-throw), DPDT (double-pole double-throw), and DPST (double-pole single-throw).The working principle of the APG2-9739-7 is bimetal technology. This type of technology uses two dissimilar metals that are bonded together and then heated by the current that is flowing through the circuit. The two metals expand at different rates due to the slight differences in their expansion properties, which causes the metal strips to bend and, ultimately, to snap shut. When the circuit breaker trips, the current flow is stopped and the circuit breaker can then be reset manually.The APG2-9739-7 has many practical applications. It is commonly used in the construction of air-conditioners, industrial equipment, lighting, motors, pumps, and other electrical equipment. It is also commonly used in the correction of wiring errors and abnormal operation. The breaker is rated for a maximum voltage of 250 VAC and a current range of 5 to 40 amps.The trip current, or tripping time, is adjustable on the APG2-9739-7. This feature allows the user to set the trip time to meet the needs of different applications. The trip time is determined by multiplying the current rating by the set value, and this calculation is generally adjustable with a screwdriver.The APG2-9739-7 is an important component of circuit protection, providing protection from overvoltage, overcurrent, and short circuits. It is designed to be reliable and long-lasting, with a life expectancy of up to 100,000 operations. It is also UL recognized and CSA certified, which provides a level of assurance that it meets the safety standards required.In conclusion, the APG2-9739-7 is a versatile circuit breaker that is used in many applications. It is designed with bimetal technology to act as a trip switch when an overload or fault occurs in the circuit. It is adjustable, reliable, and long-lasting, and is UL recognized and CSA certified. This makes it an important component of circuit protection, ensuring the safety of both people and equipment.
