The dual power automatic switch is a newly developed miniature household power switch, which is mainly used to test whether the main power supply or standby power supply is normal. When the normal power supply is abnormal, the standby power supply starts to work immediately, which ensures the continuity, reliability, and safety of power supply. This product is specially designed for household rail installation and is specially used for PZ30 distribution box.

Product Overview

The dual power automatic switch is used to switch between two power sources. It is divided into common power supply and standby power supply. When the common power supply is powered off, the standby power supply is used. When the common power supply is called, the common power supply is restored), if you do not need automatic switching in special circumstances, you can also set it to manual switching (this type of manual / automatic dual-use, arbitrary adjustment).

General

YCM7, YCM7RT, YCM7T/A, YCM7RE series circuit breaker is a new generation of breaker. This breaker is applied for the distribution network of AC 50Hz, rated insulation voltage 800V, rated working current up to 800A, which is for electric energy distribution, circuit protection, protection power supply facility from destroying by the fault of overloading, short circuit and undervoltage, meanwhile it is also used for protection from unfrequent starting, over loading, short circuit and undervoltage of the motor.

The YCW1i series intelligent universal circuit breakers are designed for AC 50Hz distribution networks with a rated voltage up to 400V/690V. Covering a comprehensive current range, they serve to distribute electrical energy and provide reliable protection against overload, undervoltage, short circuit, and single-phase grounding faults. The series features intelligent protection functions with precise selectivity, enhancing power supply reliability and preventing unnecessary outages. Equipped with an open communication interface, these breakers support remote monitoring and control (“four remotes”), making them suitable for integration into modern automation systems and control centers. Compliant with IEC 60947-2 standards, they can also be used for infrequent line switching under normal operating conditions.

YCQ6s Series Automatic Transfer Switch provides reliable automatic changeover between normal and standby power sources. With 16A–630A rated current, AC 400V operation, and PC-class design, it is suitable for power distribution, generator backup, and dual power supply applications.

YCM3 Series moulded case circuit breaker,is new products,with small compact, modular,high break,double breakpoints,zero arcing,green environmen protection.Suitable for AC 50Hz,60Hz,rated operating voltage 690V and below, rated current 12.5A to 1600A distribution network,used to distribute electrical energy and protection lines and power supply equipment from overload,short circuit and undervoltage failure hazards.It can also be used as a non-frequent conversion of the line under normal conditions and in the infrequent start of the motor.

YCQ6 Automatic Transfer Switch ATS is used for automatic or manual changeover between main and standby power sources in low-voltage distribution systems. It supports AC400V, 50/60Hz systems and covers rated current from 16A to 3200A.

It is suitable for utility-generator or main-standby power transfer in hospitals, banks, high-rise buildings, industrial facilities, and other critical power supply applications. The product supports automatic control, remote electric operation, emergency manual operation, and emergency disconnection, meeting the requirements of reliable and safe power transfer.

Standard: IEC 60947-6-1

The YCM6i series molded case circuit breakers(hereinafter referred to as circuit breakers)are suitable for AC circuits with a frequency of 50Hz(or 60Hz).Their rated insulation voltageis 1000V(800V for the YCM6i-63 model),rated working voltage of 400V/690V,and ratedworking current up to 1000A.They are used for infrequent conversion of circuits and infre-quent starting of motors.The circuit breakers have overload,short-circuit,and undervoltageprotection functions,which can protect lines and power supply equipment from damage.
According to their rated ultimate short-circuit breaking capacity,the circuit breakers are di-vided into Type L(standard type)and Type M(high breaking type).
The circuit breakers feature small size,high breaking capacity,short arcing time,and vibra-tion resistance.
Compliance with standards:IEC 60947-2.
The circuit breakers allow reverse incoming lines.

YCQ7B-63 Automatic Transfer Switch (ATS) is applicable to three-phase four-wire dual-power supply grids with AC 50Hz, rated operational voltage AC 400V and rated operational current up to 63A. It can automatically transfer one or several load circuits from one power source to another to ensure the normal power supply of load circuits. This product is suitable for relatively important places such as industrial and commercial areas, high-rise and civil residential buildings.

Standards:IEC 60947-6-1
