Construction Characteristic & Operating Principle

Pullthe handle of the leakage circuit breakers to the ON position, through mechanical contacts to static contact agencies to promote reliable contact with the circuit. When the circuit with overload fault, overload curent bimetal bend and push the latch locking mechanism makes the mechanical reset, the moving contacts quickly let the static contact,so that to achieve sub-line functions; when short- circuit fault occurs , the short-circuit current make instantaneous release action, pushing the lock mandrel core mechanical action to achieve the lock breaking function; when leakage and electric shock occurs, the signal from zero sequence sensor makes the thyristor leakage release core action , puter push the circuit breaker trip to cut of the power leakage circuit breaker in a short time, thereby achieve leakage protection.

Structural Features

1. Small, tight structure, price is better than similar products.

2. Housing and some functional parts are made of high fire-resistant.heat resistant, impact resistant material.

3. Directly with the zero wire installation,avoid the electric shock hazard which caused by zero line connection errors

4. Using the latest circuit design and high-performance electronic components, has strong abilty to withstand when the impact of current and surge of over-voltage.

5. Mounted by standard rail track, convenient and save time.

Use and Maintenance

a. Push up the handle to the position "ON" to switch on, Pull down the handle to the position "OFF" to switch off.

b. Residual current protection features is tested and adjusted by the manufacturer,users can not adjust the product at random during usage.

c. After running for a period of time, the ELCB should be inspected periodically (Every other month), the test button in power on position to confimm the residual current protective properties is reliable or not.

d. Zero wire must connect to N side to keep its normal work and protective effectively.

Attention

a. ELCB must not be wetted of soaked by rain, snow or waterduring of transportion, storage and usage.

b. The product can't protect the risk of electric shock that caused by two lines contact protection circuit meantime.

c. The products must not test by short circuit between live wire and ground in case of electric shock hazard.
