3120-F321-H7T1-W19LG3-X3120-U0001M-20A

Circuit breakers are vital components in any electrical system, and they are especially useful for those working with high-voltage power sources. The 3120-F321-H7T1-W19LG3-X3120-U0001M-20A is a circuit breaker that is designed to protect against overloads in high-voltage electrical systems. It is a single-pole, surface-mounted circuit breaker that features a push-to-reset type of operation. As a Type 1 circuit breaker, it meets UL 489B Standard for Safety, allowing it to be safely used in domestic and commercial applications.

The 3120-F321-H7T1-W19LG3-X3120-U0001M-20A circuit breaker provides protection against overvoltage, undervoltage, and overcurrent. It has a thermal rating of 10 A at 240 V AC and 125 V DC, and it can withstand up to a 25 A load. The maximum surge current that it can handle is 12,000 A. The circuit breaker is designed to quickly respond to any fault that is detected, meaning that it can shut off power in as little as 10 milliseconds.

The 3120-F321-H7T1-W19LG3-X3120-U0001M-20A circuit breaker is made up of two main parts. The first is a contacts mechanism, which is a set of movable contacts that open when an overload is detected, thus breaking the circuit. The second part is a trip mechanism, which is responsible for sensing the overload and then sending a signal to the contacts mechanism to open the circuit. This trip mechanism is made up of various components, such as a thermistor, a relay, and a temperature sensor.

The application field for the 3120-F321-H7T1-W19LG3-X3120-U0001M-20A circuit breaker is wide. It can be used in residential, industrial or commercial applications that require an overload protection device. It is suitable for indoor use, as it has an IP20 rating. It can also be used in conjunction with other circuit breakers or fuses to provide a more comprehensive protection system. These circuit breakers are also suitable for applications that involve high inrush current, such as those found in heating and cooling systems.

In conclusion, the 3120-F321-H7T1-W19LG3-X3120-U0001M-20A circuit breaker is a reliable and efficient circuit breaker for protecting against overloads in high-voltage electrical systems. With an IP20 rating, it is suitable for indoor applications and can be used with other circuit breakers or fuses to provide comprehensive protection. Its thermal rating of 10 A at 240 V AC and 125 V DC and its ability to shut off power in as little as 10 milliseconds make it an ideal choice for any safety-conscious project.
