NT lowvoltage H.R.C.fuse features light in weight,small in size,low in power lossand high in breaking capacity.This product has been widely used in overload andshort circuit protection of electric installation.This product conforms to IEC 60269standards with all of the rating at the world advanced level.
General
YCM8 Series circuit breakers were developed according to the demand of domestic and international market as well as features of similar products.
Its rated insulation voltage up to 1000V, is suitable for AC 50Hz distribution network circuit whose rated operation voltage is up to 690V, rated operation current from 10A to 800A. It can distribute power, protect the circuit and power supply devices from the damage of overload, short circuit and under voltage, etc.
This series circuit breaker feature small volume, high breaking capacity and short arcing. It can be installed vertically (namely vertical installation) and also installed horizontally (namely horizontal installation).
It complies with standards of IEC60947-2.
The YCQ1F series automatic transfer switch consists of a load isolation switch (without overload and short-circuit protection mechanism) and an intelligent
controller. The switch adopts an excitation type transfer mechanism, which provides faster switching speed.
It also employs a new microcomputer control system for intelligent monitoring and control, strong electromagnetic compatibility, long-term continuous operation, and stability and reliability.
The split-type product can be equipped with an LCD display controller, which is easy to operate, has clear indications, and provides a user-friendly human-machine interface.
General
YCQ9E series automatic transfer switch, rated working curent 16A to 630A,to be used in pow- er systems for ensuring the continuity of the supply, by transfering a load between two power supply sources. The switch has three working posions of “Main ( I ) cosing”, “Standby ( II )
closing” and “Double-of (0)”, which can be used for fire-fighting linkage and infrequent con-
necion and disconnecion of power supply systems. Mainly used in hospitals, shopping malls, banks, chemical industy, metalurgy, high-rise buildings, military facilities and fire-fighting occa- sions where power failure is not allowed.
Standards: IEC 60947-6-1
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.
