The Leviton LB-120-GFR Branch Circuit Breaker is a 1-pole, 20 Amp, 120-volt thermal magnetic device designed for use in General-Use and General-Purpose applications. This breaker is equipped with Ground Fault Circuit Interrupter (GFCI) protection, providing an additional layer of safety against electrical hazards.
This breaker features a thermal-magnetic trip unit, which employs both thermal and magnetic sensing elements to detect and respond to overload and short circuit conditions. The thermal element monitors the temperature rise of the wire, while the magnetic element responds to the current flow. When the combined thermal and magnetic trips are reached, the breaker trips to prevent potential damage to the circuit and electrical appliances.
The Leviton LB-120-GFR breaker is listed to UL 489 and UL 1699 standards, ensuring compliance with the latest safety and performance requirements. It is suitable for use in 120-volt branch circuits and is designed to fit standard single-pole breaker panels.
The breaker's GFCI functionality makes it an excellent choice for protecting outlets and appliances in areas prone to moisture, such as kitchens, bathrooms, and garages. The GFCI feature provides protection against ground faults, which can cause electrical shocks and even electrical fires.
This breaker is constructed with a rugged and durable design, ensuring long-lasting reliability. It is also RoHS compliant, meaning it is free of certain hazardous materials. The LB-120-GFR breaker is easy to install, with a simple slide-in design for quick and secure mounting in the breaker panel.
In summary, the Leviton LB-120-GFR Branch Circuit Breaker is a high-performing and safety-focused device suitable for use in a wide range of applications. Its 120-volt, 20 Amp rating, thermal-magnetic trip unit, and GFCI functionality make it a versatile and reliable solution for protecting electrical circuits and preventing electrical hazards.
1. **GFCI Protection:** The primary advantage of the Leviton LB-120-GFR breaker is its Ground Fault Circuit Interrupter (GFCI) feature. GFCI protection is crucial in areas where water and electricity may come into contact, such as bathrooms, kitchens, garages, and outdoor spaces. It helps prevent electrical shocks and fires by detecting and interrupting the power flow when a ground fault is detected.
2. **Thermal Magnetic Overload Protection:** This breaker also offers thermal magnetic overload protection, which safeguards against overheating and potential electrical fires. The thermal element in the breaker senses the temperature rise caused by an overload condition and trips the breaker.
3. **UL Listed:** The Leviton LB-120-GFR breaker is UL listed, ensuring it meets the safety and performance standards set by Underwriters Laboratories. This certification provides peace of mind for homeowners and electrical professionals.
4. **120-Volt Rating:** With a 120-volt rating, this breaker is suitable for most residential applications that require standard household voltage.
5. **1-Pole Design:** The 1-pole design of the breaker means it can be used for single-phase, 120-volt circuits.
6. **20 Amp Rating:** The 20-amp rating makes this breaker suitable for circuits that require a moderate amount of current, such as those serving outlets, small appliances, and lighting.
Cons:1. **Limited Applications:** The Leviton LB-120-GFR breaker is designed for 120-volt, single-phase applications. It may not be suitable for three-phase or 240-volt circuits.
2. **Cost:** Compared to standard non-GFCI breakers, GFCI breakers like the Leviton LB-120-GFR typically cost more due to their additional safety features.
3. **Installation Complexity:** Installing a GFCI breaker may require additional steps compared to a standard breaker, such as testing the unit after installation to ensure proper functionality.
Conclusion:The Leviton LB-120-GFR 1-Pole 20 Amp 120-Volt GFCI Branch Circuit Breaker offers valuable safety benefits by providing both GFCI and thermal magnetic overload protection for 120-volt, single-phase circuits. While it may cost more than a standard breaker, the added peace of mind and potential safety advantages make it an attractive option for homeowners and electrical professionals.
Recommendation:If you are working on a residential project that requires a 120-volt, single-phase circuit with GFCI protection, the Leviton LB-120-GFR breaker is an excellent choice. Its UL listing, thermal magnetic overload protection, and GFCI functionality make it a reliable and safe option for various applications, such as bathrooms, kitchens, garages, and outdoor spaces.
