Photovoltaic Grid-Connected Automatic Reset Switch, Photovoltaic Recloser Jgb1-125

Introduction

The JGB1-125 photovoltaic grid-connected automatic reset switch is mainly used in photovoltaic power generation combiner boxes. During the day, when the photovoltaic power generation voltage is normal, the product automatically closes, feeding the electricity generated by the photovoltaic system into the power grid. At night, when the photovoltaic power generation voltage is lower than normal, the product automatically opens, preventing electricity in the power grid from returning to the photovoltaic power generation equipment and burning it out.

Scope of Application

The JGB1-125 photovoltaic grid-connected automatic reset switch is suitable for AC 50Hz, rated voltage 230V (1P+N, 2P), 400V (3P+N, 4P). It provides overload and short-circuit protection for circuits. It can also serve as infrequent operation of the circuit under normal conditions, and is widely used in intelligent upgrading of power grids.

Main Functions and Technical Parameters

A red signal indicator light is provided on the front of the product; the indicator light stays on when the main circuit is energized, and is off when the main circuit is de-energized. It automatically opens when power is lost (after opening due to a power failure, 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
