JC80-4P Miniature Circuit Breaker

Connect L to the left side and N to the right side of the incoming terminal of the single-phase circuit breaker; The incoming terminals of the three-phase four wire circuit breaker are 1, 3, 5, N from left to right, that is, the neutral line is connected to the right side of the product, and the control unit of the circuit breaker is located on the left side of the product;

The front of the circuit breaker is equipped with a red fault indicator light, which displays different indicator states for overvoltage, undervoltage, and phase loss (limited to three-phase four wire circuit breakers) on the power side to identify the current voltage status on the photovoltaic distribution line (see Table 4)

The judgment of power supply voltage on photovoltaic distribution lines and the control action status of circuit breakers in "automatic" and "manual" modes meet the requirements of Table 5
