Global 3phase Switch DC Contactor with Short Circuit Protection

Global 3phase Switch DC Contactor with Short Circuit Protection

Brief introduction:

The unit integrates sensible meter, reclosed circuit breaker, and wi-fi collector. It can realize high-precision metering of one-stage/three-phase AC energy offer circuit, and a built-in power control of numerous intelligent logics.


  1. Defense purpose: Keep an eye on the electrical power usage of the output terminal and instantly lower off the energy offer if an abnormal predicament occurs.
  2. Automated coincidence: Realize computerized reclosing in unattended environment after the line returns to standard.
  3. Metering operate: With higher-precision voltage and present genuine-time checking and power metering, which will help to analyze energy consumption of the electric power products.
  4. Wi-fi interaction: With local RS485 conversation and GPRS (2G / 3G) wireless communication, it can comprehend distant opening and closing handle, fault inquiry and timing reporting of measurement info.
  5. Devices management: With ideal fault issue monitoring (overload, brief circuit, more than voltage and underneath voltage, section reduction, period imbalance) and can report and give alarm prompts in genuine time.
  6. CZPTity management: With a price measurement in accordance with the nationwide standard and can realize freezing data operation. Combined with wi-fi conversation, distant management of electrical power charges can be recognized, and if arrears, the loop will close and all the devices will quit functioning.
  7. Xihu (West Lake) Dis.nized show interface: With an outsized Lcd screen for distant and neighborhood data communication. The metering parameter and device status data is obvious at a glance.

Unlock release

Determined the circuit fault, the electrician need to pull out the safety lock and dangle with a lock to solve the issue. Then, push back again the safety lock, and try out manually switching on the deal with. If unsuccessful, electrician demands to examine credit rating overdue or remotely switched off, by possibly RS485 or GPRS.

Safety lock

It is beneath procedure manner whilst security lock not pulled out.
It is underneath upkeep method whilst basic safety lock is pulled out and demands to cling a lock. This safety lock has interlock with manage, and can’t swap on, even manually, whilst lock pulled out. A lot more stability to upkeep electrician.
