一、summarize
DRNL-32 is a new product independently developed by our company (this product integrates the advantages of the same type of product) has the advantages of compact structure, small size, excellent performance, small size, high breaking capacity, and full protection function. Products comply with GB16917.1, Gb10963 and other standards, in a similar product in a leading position.
二、 scope of application
DL7NL-40 leakage circuit breaker (hereinafter referred to as leakage circuit breaker) (phase line + neutral line + leakage) protection circuit breaker is suitable for AC 50Hz or 60Hz, rated voltage 230V single-phase residential circuit, as a leakage protection, It also protects the overload and short circuit of the civil electric circuit. The product has a high capacity for small volume breaking. The zero and fire lines are cut off at the same time, and even if the fire line is reversed, the leakage can still be protected. This product complies with IEC61009/GB16917.1 and other standards.

六、installation and wiring diagram
Read carefully before installation and install it correctly
1 pull down the DIN rail, install the card
2 Lift it up while tilting the unit
Note: When the DIN rail mounting card is pulled out, it will be locked. Therefore, before reinstalling the unit on a DIN rail, push it inward.
