Definition: The L7 photovoltaic DC circuit breaker is a miniature circuit breaker suitable for circuits with an AC frequency of 50Hz/60Hz, a rated working voltage of DC500V, DC1000V, or DC1500V, and a rated current up to 63A.
Application: It is mainly used in industrial, commercial, high-rise, and residential buildings, serving as a means for infrequent connection, disconnection, and switching of distribution lines, providing overload and short-circuit protection for lines and equipment. 
Installation method: Usually installed on TH35-7.5 mounting rail, with installation category being II and III.

Main Parameters 
Rated current: There are multiple options available, including 1A, 2A, 3A, 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, and 63A.
Rated short-circuit breaking capacity: Generally, there are two options: 6kA and 10kA.
Pole number: It includes single-pole, two-pole, three-pole, and four-pole. The rated voltage of single-pole circuit breakers is 230V, while that of two-pole, three-pole, and four-pole circuit breakers is 400V.
Instantaneous tripping current form: There are three types: B, C, and D.
