Smart Mccb High Breaking Capacity Intelligent HWM2EL Smart Moulded Case Circuit Breakers Wifi

1.Long time delay,short time delay and instantaneous time protection,it applies electronic tip,and has no concerns with power voltage.

2.it owns high breaking capacity.to guarantee the reliability at short circuit protection in lies.

3.it owns protection of over voltage,under voltage,phase loss;

4.In real time to display the residual current,three phase power voltage.and load current:

5.The protection function and parameter can be setup and modified online.

6.Trip types(residual current,lock,overload,under voltage,over voltage.phase loss),recognize,display,and can be restored,check and deleted;

7.Network type owns communication function,it can realize remotely communication,measure,control,and adjust.

Auto Reclose

While the resi dual current exceeds action current value gear and trip, the device will auto reclose after 20-60 seconds, while manually reclose is not imited. The device reclosed for 5 seconds and the circuit taulty disappeared. it reclose successtully, and the breeker runs nomally; Otherwise. the device will trip and lock itl circult tauly not removed, The device won’ t aulo feclose and requires manually operation to teclose.

Over voltage Protection

While the line voltage is higher than the setup protection value, the breaker will trip. While the line voltage recovers to normal, the breaker will auto reclose and run. The voltage satup value range is. 250-300V. normally, setup 280V while manufacture. The customer can set up or clase this protecton as needed.

Under vltage Potectin

While the line vllage is lower than the setup protection value,the breaker will trip.While the line vllage recovers to normal,the breaker will auto reclose and run.The vltage setup value range is 150-200V.normally setup 170V while manufacture,The customer can set up or close this protection a8 needed.

Phase Loss Protection

While the line terminal has phase loss, the breaker will trip. The breaker will auto reclose and run while the phase loss clrcult faulty disappears.

Interink Communication Protection

This device may connect with other fire extinguishing equipment and owns protection as below.
