Product Information

1. Overview

SDLB-9FII series leakage relay was invested to resolve the prior similar rudimentary products which has single function, especially could not protect the overload in distribution. It also solved the problem of lacking display on the distribution box. It has the fuction of leakage protection, auto reclosing and overcurrent protection, can displaies the value of three-phase load current, voltage, leakage current and so on.

It has been recognized as the national Torch Program projects in China, and be widely used in the project of "Smart Gird" in the State Grid at China.

It conforms with the standards of IEC61009 and GB14048.2-2008.

2. Application

This relay and combined with AC contactor or circuit breaker could be combined into a set of current leakage protector. SDLB-9FII series leakage relay is applicable to a line of AC 50Hz/60Hz, rated voltage 380/220V for neutral-point direct grounding low voltage distribution system. It can protect the line from ground fault. It can also be used for indirect protect people from potentially deadly electrical shock hazards.

3. Main Function

● Transformer protection(enable with current transformer) and auto reclosing

● RS-485 communication interface was designed to make the system capable of net communication

● Manual adjustment of residual operating current value, or self-regulate the residual operating current value as the line leakage

● Query-able for all previous tripping time, fault current

● Account the data of maximum load current per month, the data will be stored safely for 12 months(enable with current transformer)

● Adjust the overload protection value as the capacity of distribution transformer or the actual load (enable with current transformer)

● Account the times of trip(previous, current month and total)

● Digital display the value of three-phase currents(enable with current transformer), voltage(Optional), leakage current

● Be able to identify and separate surge leakage current(Optional)

Company introduction: Hangzhou Tianmu power technology Co., Ltd(formerly Hangzhou Lin'an Leakage Protector Manufacturer), as a share-holding enterprise specialized in research and production of low voltage device, application software. It is the vice-president unit of the Zhejiang Breaker Association, the province-level Zhejiang High-tech enterprise, and the Hangzhou patent demonstration enterprise.
In the past 30 years, we had been devoting ourselves in the undertaking of rural electrification, we provide high quality intelligent leakage protector for the construction of the state smart grid and the management of the power grid.
Company leading products: the tertiary residual current protector(the series of SDLB/TZB/TML/TCM1/TM47LE), the remote control leakage protector, comprehensive low voltage power distribution cabinet, electric meter box, and others intelligent supporting product.
We have professional technicians, and modern assembly line, and we have the conditions for scaled production. We have been keeping the tenet "quality first, technological innovation" since inception. We emphasized technical input and have been awarded over 20 national patents. Multiple techniques are the first in the domestic product, and filled the blanks of breaker industry.
The company was identified as High-tech enterprises in Zhejiang Province, took the lead in conforming to ISO9001 international quality management system certification, and we are the Research and Development Base of Zhejiang University. Our products were the first to obtain the national "3C" compulsory certification, and were awarded the titles of "Famous product in Hangzhou", "Famous brand in Hangzhou" and "national torch project". They are widely used for the accessory elements of the construction of state grid’s electricity distribution networks.
Our company take "quality assurance, integrity service" as the management idea, have set good image in the market, and distribute our product to all the Zhejiang province and sell well all over the country. We have set up many branches and agencies in different provinces and cities.and provide excellent professional after-sale services.
"Tianmu Technology" will always stick to the business ideas of Survive with Quality , Develop with Science. We are continuously seeking to develop electricity technology with colleagues in new attitude of New beginning, New opportunities, New Development. We will have full confidence and make efforts to build an efficient team to create a modern enterprise, get the domestic leading and industry-leading position.
