DZ47LED-63 lightning protection residual current circuit breaker

DZ47LED-63seriesLightning protection leakage switch（Lightning protection residual current circuit breaker）It is a small device with lightning protectionLeakage circuit breakerSuitable for lightning protection, surge protection, leakage protection, short circuit protection, and overload protection in distribution networks with AC voltage of 380V and below and frequency of 50Hz. And it can be used for infrequent switching of lines under normal circumstances.
Implementation standards for lightning protection residual current operated circuit breakers (RCBOs) with overcurrent protection for household and similar use: GB16917.1 Part 1: General rules GB188022 IEC61643-1 and GB 500057 "Code for Design of Lightning Protection of Buildings".

The lightning protection residual current switch is composed of a surge protection module (SPD) added to a small residual current circuit breaker, which has relative ground and neutral to ground protection modes. Especially suitable for situations that require multiple protections. This product consists of three SPDs and one gas discharge tube BL forming the main discharge circuit. The three SPDs are connected in series with the L1, L2, and L3 poles (live) and the N pole (neutral) of the gas discharge tube, and then connected to the earth (PE) to discharge lightning through the earth (PE), thus protecting the load end of the switch from lightning damage. During normal operation, the green light is on and the red light for fault issues is on.

■ Tripping indicator: There is a residual current action tripping indicator on DZ47LE, and the reset button pops up, indicating leakage tripping
■ Manual control: The handle allows for two reset modes
Overcurrent fault: circuit breaker and residual current action device reset simultaneously
Leakage fault: residual current action device resets first, circuit breaker resets later
□ Lightning protection fault: The lightning protection device is reset first, followed by the circuit breaker

1. The lightning protection, leakage, overload, and short-circuit characteristics of lightning protection residual current circuit breakers are set by the manufacturer and are not allowed to be adjusted arbitrarily during use.
2. Lightning protection residual current circuit breakers must be tested by pressing the test button before being installed or used again after a power outage to ensure normal tripping. Under normal use, they must be tested for tripping once a week.
3. When using electric tools and equipment within the protection range of lightning protection leakage switches, the test button must be pressed to ensure normal tripping before they can be put into use.
4. After humid weather or thunderstorms, the test button must be pressed before each use to ensure normal tripping before being put into use.
5. If the lightning protection leakage switch has a fault or cannot trip by pressing the experimental button, please stop using it immediately and send it back to the manufacturer for repair as soon as possible.
6. After the lightning protection leakage switch is opened due to a malfunction of the brake system, the cause must be identified and the fault must be eliminated before it can be closed.
7. The lightning protection leakage switch cannot provide protection against the risk of electric shock caused by simultaneously touching two wires of the protected circuit.
8. According to the national standard, the function of a leakage protector is to provide indirect contact electrical protection. When other protective measures fail... it cannot be used as the only direct contact protection.
