Circuit breakers are safety devices in electrical systems and can be found in many homes, offices, and businesses. They are designed to protect the system from overcurrent or short circuits and to act as a pathway for a quick shutdown or reset if something goes wrong.

The LEG66-34870-20-V circuit breaker is an example of a type of circuit breaker and is an example of a newer generation of circuit breakers. It is specifically designed for use in photovoltaic systems and is UL508 listed. It incorporates an advanced electronics technology that enables it to operate at high current levels with much more flexibility and efficiency than traditional circuit breakers that reliant on mechanical switches alone.

The LEG66-34870-20-V circuit breaker offers a simple and reliable means for protecting dc photovoltaic systems from overcurrent, short circuiting, and overloads. It has a maximum current rating of 20 amps and a maximum operating temperature of 70°C. The circuit breaker uses an extremely sensitive solid-state current and voltage sensing system to quickly detect and disconnect a circuit when it becomes overloaded.

The LEG66-34870-20-V circuit breaker also has a unique field-installable feature which allows the user to easily modify the settings of the circuit breaker to manage the current and power needs of the system. This feature eliminates the need for the user to purchase separate circuit breakers for different applications. The circuit breaker also prevents current or voltage fluctuations from impacting the system as well as offering reverse flow protection.

The solid-state sensing system of the LEG66-34870-20-V circuit breaker protects the system by operating with a minimum current or voltage set point of 1.3 amps and 14.4 volts respectively. The system is designed to detect any deviations from the set points and disconnect the circuit accordingly to protect it from damage. The system also includes a manual override switch which allows the user to override the automatic current or voltage sensing mode, allowing the user to manually disconnect the circuit if needed.

The LEG66-34870-20-V is designed for use in photovoltaic systems with DC input current not exceeding 20 amps and voltages up to 600 volts DC. The device is designed to operate without resetting or tripping until the current reaches an unsafe level. The LEG66-34870-20-V has a high level of reliability and is UL508 listed for use in photovoltaic systems.

In conclusion, the LEG66-34870-20-V circuit breaker is a reliable and efficient safety device designed for usage in photovoltaic systems. It features a solid-state current and voltage sensing system, manual override, and reverse flow protection, all of which help to keep the system safe and reliable. It is UL508 listed and designed for use with a maximum current of 20 amps and a maximum operating temperature of 70°C. With its innovative design and UL508 listing, the LEG66-34870-20-V circuit breaker is a great choice for anyone looking to keep their system safe and efficient.
