General
The YCRS series rapid shutdown device can shut down one ortwo string modules at maximum,with a maximum circuit current of 55A and a maximum circuit voltage of 1500VDC.It is made of PC+ABS material and hasan IP66 protection rating.Multiple interface types areavailable,induding push-through holes,pressure covers,and MC4 terminals.The internalisolation switch is certified byTUVCE.CB.SAA,andthe device is equipped with a waterproof and ventilated valve design to prevent condesation inside the housing.An advanced temperature sensor is used to detect the highest temperature inside the housing in real-time,and theswitch will automatically cutoff when the internal temperature exceeds 70 degreesCelsius.This device is suitablefor residential,industrial,and commercial photovoltaic systems.

VS1i-12 intelligent medium-voltage vacuum circuit breaker is a new type of vacuum circuit breaker developed by combining traditional vacuum circuit breaker and ‘intelligent switch equipment comprehensive monitoring device’. It adopts a new modular mechanism, ensuring stable operation and simple maintenance.

The smart circuit breaker collects data from various sensors to the intelligent processor,which integrates switch mechanical characteristics, temperature data collection, and analysis functions. The display terminal performs on-site analysis of mechanical faults, temperature rise prediction alarms, and edge computing for on-site diagnostics. It supports human-machine interaction, providing strong safeguards for safe equipment operation.

YCH8DC DC isolation switch is suitable for DC systems with rated voltage up to DC1500V and rated current up to 800A, playing a role in DC circuit isolation and helping the system operate safely and stably.

Mainly used in DC power supply systems such as photovoltaic power generation DC side,DC power supply system, DC charging pile, energy storage, etc.

The YCB2200PV solar pumping system serves to provide water in remote applicarions where electrical grid power is either unreliable or unavailable. The system pumps water using a high-voltage DC power source such as aphotovoltaic array of solar panels.

Since the sun is only available during certain hours of a day and only in good weather conditions, the water is generally pumped into a storage pool or tank for furher usage. And water sources are those natural or special such as river, lake, well or waterway, etc.

Solar pumping system is constituted by solar module array, combiner box,liquid level switch, solar pump erc. It aims at providing solutions for the region that suffers water shortage, no power supply or uncertain power supply.

YCM6, YCM6RT series circuit breaker is a new generation of breaker.

This breaker is applied for the distribution network of AC 50/60Hz, rated insulation voltage 800V, rated working current up to 800A, which is for electric energy distribution, circuit protection, protecting power supply facility from being destroyed by the fault of overloading, short circuit and undervoltage. And it is also used for protecting, overloading, short circuit and undervoltage of the motor.

This breaker has such characteristics as high short circuit interrupting capacity, shortarcing and etc., which is a ideal product for users. This breaker can be installed vertically or hori-zontally.

Standard:lEC60947-2
