The CYB3-80W photovoltaic automatic reclosing circuit breaker is suitable for use in circuits with an AC frequency of 50Hz, a rated working voltage up to 400V, and a rated working current up to 80A. It provides remote automatic closing and opening control, automatic signal-controlled closing and opening, as well as overload and short-circuit protection for the circuit. It also features power-off opening and automatic power-on closing upon incoming power. Currently, it is widely used in photovoltaic grid-connected AC distribution boxes, as well as in locations that are difficult for personnel to access, where maintenance personnel cannot be on site in a timely manner, unattended locations, and locations where high power supply continuity is required.
Conforms to standards: GB10963.1, IEC60898-1, with international advanced level.
