WPB1RL-100-B Type B residual recurrent circuit breaker is widely used in solar project especially for solar charging pile. Its tripping is ensured for sinusoidal AC residal currents pulsed DC residual currents, alternating residual sinusoidal currents up to 1000Hz, pulsating direct residual currents and for smooth direct direct residual currents, whether applied suddenly or increasing slowly.

WPB7-80DC photovoltaic DC mini circuit breaker is widely used in photovoltaic power distribution system such as photovoltaic junction box other DC electrical equipment. It is used for rated voltage DC 1000V, rated current up to 80A, with science arc and current limiting system, can be quickly disconnected from the DC power distribution system caused by the current fault, and can realize the reverse current protection to ensure reliable operation of solar photovoltaic.

WPM3 series of photovoltaic DC MCCB is widely used in large-scale photovoltaic power generation and distribution system, including photovoltaic junction box, photovoltaic inverters, photovoltaic DC cabinet etc.. It is used for rated voltage DC 1000V, rated current up to 250A, can quickly disconnect the DC distribution system caused by current fault to ensure the solar photovoltaic power generation system

Surge protector is apply for new energy solar power generation system.The maximum continuous working voltage of DC500V, 1000V and 1200V.Installed on the DC circuit power system, the indirect lightning current, DC lightning current or other transient overvoltage protection when the system or other reasons due to lightning surge overvoltage protector, immediately nanosecond time rapid conduction, the over-voltage surges into the earth, so as to protect the electrical equipment online.
DC series is plug-in structure, module failure can be quickly replaced; lightning protection module failure, the indicate window color from green to red and send the alarm signal to the remote connection which in the remote communication terminal of alarm equipment (plus add remote device).

WP18PV series DC fuse is suitable for solar photovoltaic system, rated voltage to DC 1500V, rated to current 63A used in photovoltaic power equipment as over current protection for photovoltaic modules and photovoltaic arrays, short circuit breaking protection for charge variable flow system which connected with photovoltaic panels and batteries, short circuit breaking protection for inverter rectifier system in photovoltaic station, and quick break protection caused by surging current and short circuit fault in photovoltaic power system.
