Lightning leakage circuit breaker DZ47LE-63/3PN Instructions for use
First, the main purpose and scope of use DZ47LE series of lightning leakage circuit breakers, is a small circuit breaker with lightning protection device leakage, suitable for AC 380V and below, the frequency of 50Hz distribution network, for lightning, surge , leakage, short circuit, overload protection. And can be used as normal line infrequent conversion.
Product implementation standards: GB16917.1 Residual current operated circuit-breakers (RCBO) with overcurrent protection for household and similar uses Part 1: General rules GB18802.2IEC61643-1 and GB500057 "Lightning Protection Design Code for Buildings".
Second, the structural characteristics of the product is based on the small leakage circuit breaker based on the addition of a surge protection module (SPD) constitutes, the SPD has a relatively ground, the neutral line to the ground protection mode. Particularly suitable for applications where multiple protections are required. The product consists of three SPDs and one gas discharge tube BL to form the main discharge circuit. Three SPDs are connected to the L1, L2, L3 (FireWire) and N-poles (neutral) and the gas discharge tube in series, respectively. Into the earth (PE), the lightning discharge through the earth (PE), thus protecting the load side of the switch from lightning damage. In normal operation, Run 1, Run 2, and Run 3 lights.
Third, functional characteristics:
1, with lightning protection, leakage, overload and short circuit protection.
2, with lightning protection grounding function.
3. Full-mode protection of phase to neutral, phase to ground and neutral to ground.
4, with mine failure indication function.
5, lightning current capacity up to 20KA.
6. There is an overheat protection device inside.
7. The switch uses two levels of lightning protection inside.
8, can be external alarm signal.
Fourth, the product model and meaning
V. Main technical parameters
Six, lightning protection parameters
Seven, over-current release features
Eight, dimensions and installation dimensions
Nine, wiring diagram
Tenth, use and precautions 1, circuit breaker lightning leakage overload short-circuit characteristics are set by the factory, in the use of the process is not allowed to adjust.
2. Lightning leakage circuit breakers must be pressed before the new installation and after the power is turned on to ensure that the normal trip can be put into use. Under normal use conditions, it must be tested once a week.
3, in the lightning protection circuit breaker protection range, the use of power Tools and equipment, you must try to press the button to ensure normal tripping before they can put into use.
4. After wet weather or thunderstorm, press the test button before each use to ensure that the normal trip can be put into use.
5, lightning leakage circuit breaker if there is a fault or press the experiment button can not be tripped, please immediately stop using the user, as soon as possible to return to the manufacturer for repair.
6, lightning protection leakage circuit breaker due to the failure of the electrical generator and the need to identify the reasons after the opening, troubleshooting before closing.
7. The lightning leakage circuit breaker can not protect against the risk of electric shock caused by touching both lines of the protected circuit at the same time.
8. According to national standards, the function of the leakage protector is to provide indirect contact protection. "In the event of failure of other protective measures ... cannot be used as the only direct contact protection."
