The YCFP7 Strip-Shaped Hot Aerosol Fire Extinguishing Device is designed for electrical cabinets and relatively large enclosed equipment compartments. Its elongated stainless-steel housing with red coating makes efficient use of narrow internal mounting spaces.

With six agent quantities from 50 g to 300 g, the series protects enclosed volumes of up to 3 m³ and supports both electrical and thermal activation.

The YCFP7 Round Hot Aerosol Fire Extinguishing Device is a compact, thermally activated fire suppression solution for small enclosed equipment spaces. Its circular housing is suitable for installation where internal mounting space is limited.

Available with extinguishing agent quantities from 8 g to 100 g, the series provides protection for enclosed volumes from 0.08 m³ to 1 m³.

YCP5 series AC Motor Starter is suitable for circuits the alternating voltage up to690V,current up to 80A.The product works to control theoverload,phase loss,shortcircuit protection and infrequent starts of a three-phase squirel cage asynchronousmotor.The Motor Starter can protect the distributing line for infrequent loadtransfer,and it can also works as an isolator

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.

The AFDD9RL-63 series Arc Fault Detection Device are assembled by residual current circuit breakers (RCBO) and arc detection modules. The AFDD9RL-63 Arc Fault Detection Device possess the functions of short-circuit protection, overload protection, residual current protection and arc-fault protection. They are suitable for being installed in branch circuits and can quickly cut off the circuits to play a protective role when over current, short-circuit, leakage or arc-fault occurs in the branch circuits.

The AFDD9NL-40 series Arc Fault Detection Device are assembled from 18mm – wide double – pole leakage circuit breakers (RCBO) and arc – detection modules. The products have functions of short – circuit protection, over – current protection, over – voltage protection, leakage protection, and arc – fault protection.

The AFDD9NL-40 series Arc Fault Detection Device meet the performance requirements of the standard IEC62606 – 2013. The AFDD9NL-40 series is designed in particular for UK market.

AFD9-63 , a three phase four wire Arc Fault Detection Device (AFDD), designed to reduce the risk of electric fire, can effectively detects electric arc faults, disconnects the affected circuit and offers complete protection in residential,non-residential building, energy sources, industry and infrastrutures. Installation of AFDD is strongly recommended in location with sleeping accomodations, place with fire risks due to big quantity flammable materials, place with combustible building materials, place with irreplaceable goods and beyond.

The AFDD9-63 three – phase four – wire Arc Fault Detection Device is assembled from a miniature circuit breaker(MCB) and an arc – detection module. The AFDD9-63 Arc Fault Detection Device has functions of short – circuit protection, over – current protection, and arc – fault protection. It can simultaneously detect the A – phase, B – phase, and C – phase fault arcs in three – phase circuits, and can also detect the fault arcs between phases. When the Arc Fault Detection Device detects an arc fault in the circuit, it will immediately cut off the power supply to play a protective role.

YC7VAN-WIFI kWh Voltage and Current Protector is a smart protection device that integrates remote control, energy monitoring, and multi-functional electrical protection. It supports real-time monitoring and app-based control from anywhere, with adjustable protection for overvoltage, undervoltage, overcurrent, and leakage. Users can preset voltage and current thresholds via the app, and the device will automatically cut off power when abnormal conditions occur, ensuring safe and efficient power management for residential and commercial applications.

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.
