BM7G series small isolation switch
BM7G series small isolation switches are suitable for distribution lines with ac 50Hz, rated voltage 400V and below, rated current 100A and below, for isolation of power supply and infrequent operation of power supply under load.With dual function terminal, the terminal terminal wiring capacity up to 50mm 2 , and can be padlocked to prevent misoperation.
BM7FL series residual current operated circuit breakers without overcurrent protection (electromagnetic)
BM7FL series residual-current action circuit breakers without overcurrent protection are suitable for use in household and similar applications with rated working voltage up to AC400V 50Hz and rated current up to 80A.This product and the circuit breaker work together, can play overload and short circuit protection function, strong anti-interference ability, the residual current action form is electromagnetic, action performance and the main circuit voltage independent, reliability is higher.
BM71FL series residual current operated circuit breaker with over current protection (electromagnetic type)
BM71FL series residual current operated circuit breakers with over-current protection are suitable for household and similar uses with rated working voltage up to AC230V, AC 50 Hz and rated current up to 40A. The product has overload and short circuit protection function, strong anti-interference ability, residual current action form is electromagnetic, action performance has nothing to do with the voltage of the main circuit, higher reliability.
BMQ1 series double power automatic transfer switch (CB class ATSE)
BMQ1 series double power automatic transfer switch is CB grade product independently developed and manufactured by MINGRI .A reversible motor and driving mechanism are used to drive two circuit breakers as the main body of dual power supply, and the dual power supply is automatically converted through the controller. Circuit breaker itself has the function of over current protection, compared with similar products, with small volume, low cost, high performance, high reliability and other characteristics. Used for ac 50Hz, rated working voltage ac 400V and below, rated working current to 800A two-way power supply system (grid-grid, grid-generator set).When the power supply of one circuit fails, it can be automatically converted to the other circuit to realize the automatic conversion between the common power supply and the standby power supply. It is widely used in hospitals, shopping malls, Banks, chemical industry, metallurgy, high-rise buildings, military facilities and other important occasions where power failure is not allowed. In 2014, the company added bmq1w-100g dual power automatic switching device, which is a pc-level dual power supply with BMG isolation switch as the actuator.
BMQ2 series dual power automatic transfer switch (PC level ATSE)
BMQ2 series automatic switch is a high-end product with international quality independently developed, designed and manufactured by Mingri. It consists of three parts: main engine, control system and connecting wire harness .Applicable to ac 50Hz, rated insulation voltage 800V, rated working voltage AC400V and the following two power supply system. When one power supply fails, it can quickly transfer the load to the other power supply and realize automatic conversion between the two power supplies to ensure the continuity and reliability of power supply. It is widely used in the important power supply system with higher demand for power reliability. Such as hospitals, shopping malls, Banks, civil air defense, chemical industry, metallurgy, High-rise buildings, military facilities, scientific research institutions and fire fighting and other important places that are not allowed to lose power.
BMQ5 series automatic transfer switch (distribution ATSE product)
Automatic transfer switch is a kind of power conversion equipment which is used more and more widely. It is composed of automatic transfer switch and controller. In case of voltage loss, under voltage, over voltage, phase loss, over frequency, under frequency and other faults in common power supply, it can quickly transfer important load from common power supply to standby power supply, so as to ensure the continuity and reliability of power supply. The product is suitable for industrial facilities and other places with higher requirements for continuity and reliability of power supply.
BMJ2 series AC contactor
BMJ2 series AC contactor, it is mainly used for AC 50 hz or 60 hz, the rated insulation voltage to 660 v, used in AC - three categories, the rated working voltage of 380 v when the rated working current of 9 a ~ 95 a circuit, for long-distance connected and breaking circuit, frequent starting and control of AC motor, and with the appropriate composition of thermal overload relay electromagnetic starter may occur in order to protect the load circuit.
