Smart Circuit Breaker

WE-H4 series

【Attentions】

This device must be installed by qualified electrician, and is not allowed to open device;

Don’t operate device with wet hands, otherwise, electric shock may occur;

         This device is not have waterproofed ,do not use it in humid environment;

The safety lock should be pulled out while installation;


      This device will enter “LOCK” mode while circuit has fault of overload, short circuit or manually switch off. The unlock process is to manually pull out the safely lock, identify and solve the circuit fault problem. Release safety lock, and manually switch off/on once, it will work.



Product description

The Smart Circuit Breaker WE-H4 series is a highly centralized intelligent electric device that integrates electric energy monitoring, overload, short circuit, over-voltage, under-voltage protection, remote control opening and closing, and network communication functions. It consists of 1gateway and several Schneider circuit breakers, and the circuit breakers do not affect each other and can be controlled and measured separately. Internal functions can be selected according to needs.



◆ Multi-channel control: 1 gateway can carry up to 20 circuit breakers;

◆Protection function: monitor the power consumption of the output terminal, and automatically cut off the power supply in case of abnormal conditions;

◆ Automatic reclosing: automatic reclosing after the line returns to normal;

◆ Metering function: high-precision real-time monitoring of voltage and current and energy metering, which is conducive to energy consumption analysis on the power consumption side; according to different scenarios, the power threshold setting of different branches can be carried out to realize remote opening and closing.

◆ Wireless communication: With local RS485 communication and 4G wireless communication, it can realize remote opening and closing control, fault inquiry and timing report of measurement data.

◆Equipment management: It has complete fault status monitoring and real-time reporting and warning prompt.

◆Electricity fee management: it has metering that meets the national standard, freezing data, etc. Combined with wireless communication, remote management of electricity bills can be realized, and the arrears can be closed.

◆Humanized display interface: With a large LCD screen display, it can realize remote and local information exchange. The metering parameters and equipment status information are clear at a glance.

Product composition

gateway


Main function

ØThe gateway actively reports events

ØFault alarm type: send fault only once

ØOver-current protection, overload protection, over-voltage protection, under (loss) voltage protection, leakage protection, event type, remote close, remote open, local close, local open, leakage protection test, normal mode, remote lock control, local lock control

ØCommunicate with sub-devices (smart circuit breakers)

ØThe communication interface with the sub-equipment is RS485 wired mode

Ø◎The ID address allocation of sub-devices is from left to right

Ø◎Every time you add or delete a sub-device, you need to re-allocate the address

ØUnder normal communication, when the sub-device does not respond or responds to the operation of the wrong gateway host, the gateway marks the device as offline
