iALM1L series intelligent residual current operated circuit breaker (hereinafter referred to as leakage circuit breaker) is an integrated, multifunctional, and current adjustable leakage circuit breaker. it is applicable to the low-voltage power grid with three-phase four-wire neutral direct grounding (TT grounding system), which is used to provide indirect contact protection against human contact hazards, and also to protect the ground. ing fault, overcurrent, short circuit, etc. of lines or electricity.
◆ High-performance 8-bit microprocessor is adopted for real-time signal processing and intelligent control;
◆It supports LCD Chinese display, a friendly man-machine interface, and simple operation;
◆Long time delay, short-circuit short time delay and instantaneous three-segment protection, electronic tripping, independent of auxiliary power supply;◆Overvoltage and under voltage protection, phase loss protection, abrupt change protection, etc., with automatic reclosing function after recovery meanwhile; Residual current protection, automatic gear setting, and reclosing function;
◆ Real-time display of line residual current, three-phase supply voltage, and load current;
◆Enabling and disabling of the setting of protection functions and parameters;
◆It can monitor and record a large amount of data to facilitate maintenance and overhaul;
◆It has a communication function, and the product meets the standard: DL/20 Residual Current Device Communication Protocol;
The products are applied to low-voltage JP cabinets (integrated distribution cabinet of distribution trans. ormer) and photovoltaic power generation systems for urban and rural power grid transformation; JP cabinet is designed to meet the requirements of standardization, miniaturization, and outdoor type of rural low-voltage distribution devices. lt integrates power distribution, metering, protection (overload, short circuit, leakage. snow prevention), and capacitance reactive power compensation into one whole.
◆Ambient temperature: -15°C~ 70°C:
◆Relative air humidity: when the maximum temperature is +40°C, the relative humidity of the air shall not exceed 50%: at +20°C, the relative humidity of the air is allowed to reach 90%, and the condensation on the product surface due to temperature change should be taken into;
◆The altitude is generally not more than 2000m, otherwise it needs to be reduced:
◆The pollution level is level 3;
◆Installation category is III;
◆The magnetic field outside the installation site shall not exceed 5 times of the geomagnetic field in any direction: no explosive and corrosive gas: no invasion of rain or snow; dry and ventilated:
◆The sine wave distortion of the power supply is less than 5%.
