1 Scope of application
LRPG Series circuit breaker with residual current protection is a high-performance adjustable circuit breaker with triple protection functions of leakage, overload and short circuit. lt is applicable to AC 50/60Hz and rated voltage 230/240V. Places with rated current of 60A and below. lt is mainly used for electric leakage, overload and short circuit protection of lighting, energy meter boxes, distribution lines and equipment of residential buildings, office buildings and similar buildings, and can also be used for infrequent operation and switching of lines under normal conditions.
2)The product standard
IEC/EN 60947-2, NFC 61450
3 Product features
Compact structure, multiple rated current ranges can be selected,which can solve the problem of frequent replacement of circuit breakers due to increasing load.

5.operating principles
5.1 Service connections are the interface between the Utility and the end- user customer.
5.2 They connect the customer's electrical installation to the power distribution network.
6. Advantages
6.1 Low-cost product,suitable for conventional service connections.
6.2 Multiple rating device.
6.3 Several levels of earth leakage sensitivity.
6.4 Complies with the French NFC 61450 standard.
7. Convenience and safety

The neutral pole is designed to close first and open last to maintain a fixed potential.
7.2 Protection against nuisance tripping
Immunized against voltage surges of atmospheric origin
Uninterrupted power supply for greater user convenience
7.3 Safety checking
·The test button may be used to simulate an earth leakage fault, thereby providing a simple way to check the system.
7.4 Easy operation
Operation in all positions
ON/OFF control by push-button
Rating easily changed
lead-saleable terminal shields
captive terminal screws
pivoting terminals
copper cables up to 35 mm²
neutral identified in blue

8.Instructions for changing rated current gear
a. The default setting of the circuit breaker at the factory is the maximum current gear;
b. When replacing the rated current gear, please ensure that the circuit breaker is disconnected;
c. By observing the corresponding current indicating window, remove the gear screw at the inlet end with a slotted screwdriver (Fig. Fig.1);
d. Remove the protective cover of the incoming line end (Fig. 2);
e. Remove the middle cover, select the required current gear, and adjust the current gear (Figure 3);
f. Then install the middle cover and protective cover, and screw the gear screw to the corresponding position to ensure that the screw is tightened, otherwise the product will jump early
