A circuit breaker is a device that gets the job done between an electrical power source and a product or system. As the name suggests, it protects the power source and its downstream device from damage by quickly disconnecting the power if excessive current occurs. 3120-F301-N7Q1-W15FY0-20A is one type of circuit breaker typically used in commercial and industrial applications. It is designed to provide auto-reset and manual-reset operations and boasts excellent overload and overcurrent protection. Its precision, quick response and high reliability make it well suited for applications that involve sensitive and critical equipment.

The 3120-F301-N7Q1-W15FY0-20A Circuit Breaker is designed with an internal heat element called the overcurrent trip unit. It is connected in series in the circuit providing power to the downstream device and reacts to changes in current levels by expanding or contracting when current is present. Expansion or contraction causes the trip unit to actuate a set of contacts mounted on the circuit breaker which then cuts off the power supply and prevents further current from flowing. The circuit breaker also has a reset button which will manually reset the trip unit, allowing it to change state and restore power.

One of the key advantages of the 3120-F301-N7Q1-W15FY0-20A Circuit Breaker is that it provides both auto-reset and manual-reset functions. In auto-reset applications, the trip unit will automatically return to its normal state after the overcurrent event has been cleared and then the reset button needs to be manually pressed to reset the circuit breaker and restore power. In manual reset applications, the circuit breaker will remain in tripped state and the reset button needs to be pressed multiple times to reset and restore power. This provides greater flexibility in applications where specific reset criteria need to be met.

Other benefits of this type of circuit breaker include high contact reliability, quick response time to trip, and high accuracy settings. The breaker is also capable of multiple trip points so it can be tailored to a variety of application requirements. It has a wide range of current settings and ratings, and is UL or IEC recognized for safety. The breaker is also relatively compact in size, allowing for efficient installation in tight spaces.

The 3120-F301-N7Q1-W15FY0-20A Circuit Breaker is designed to provide reliable overcurrent protection for a variety of commercial and industrial applications. It is a UL and IEC rated circuit breaker that is capable of auto-reset and manual-reset operations and is highly accurate, quick to respond and has a wide range of current ratings. Its small size and multiple trip points also make it well suited for many application requirements.
