1. Introduction
The JGB1-125 photovoltaic grid-connected automatic reset switch is mainly used in PV combiner boxes. During the day, when the photovoltaic generation voltage is normal, the product closes automatically and feeds the electricity generated by the PV system into the grid. At night, when the photovoltaic generation voltage falls below normal, the product opens automatically to prevent electricity from the grid from flowing back into the photovoltaic generation equipment and burning it out.
2. Scope of Application
The JGB1-125 photovoltaic grid-connected automatic reset switch is suitable for AC 50Hz circuits with a rated voltage of 230V (1P+N, 2P) and 400V (3P+N, 4P). It provides overload and short-circuit protection for circuits. It can also be used for infrequent switching of circuits under normal conditions, and is widely used in intelligent upgrading of power grids.
3. Main Functions and Technical Parameters
A red signal indicator light is provided on the front of the product. When the main circuit is energized, the indicator light stays on; when the main circuit is de-energized, the indicator light is off. The switch trips automatically when power is lost (after tripping due to a power outage, the manual operating handle cannot close the switch).
1. Rated current: 40A, 50A, 63A, 80A, 100A, 125A
2. Number of poles: 2P, 4P
3. Undervoltage cutoff value: AC170V ±5V 50Hz
4. Overvoltage cutoff value: AC300V ±5V 50Hz
4. Applicable Standards
GB 10963.1 "Electrical accessories - Circuit-breakers for overcurrent protection for household and similar installations - Part 1: Circuit-breakers for a.c. operation".

Product: Pv Grid-Tied Automatic Reset Switch Photovoltaic Auto-Recloser Jgb1-125
Overview: The JGB1-125 photovoltaic grid-connected automatic reset switch is mainly used in PV combiner boxes. During the day, when the PV power generation voltage is normal, the product automatically closes and feeds the electricity generated by PV into the grid. At night, when the PV power generation voltage is lower than normal, the product automatically disconnects to prevent electricity from the grid from flowing back into the PV power generation equipment and burning it out.
