An electrical panel is the modern version of the 60-ampere fuse box, which contains 4 fuses. It serves to provide homes with 100, 200, or more amperes of power, which comes into homes from what is called a service drop. From there, it connects to the service panel's lugs and is distributed throughout the house through individual circuits. http://www.downeastelectrical.com

http://www.ilead-times.com/circuit-breaker/ Rcbo circuit breaker( MK7L-40 Residual Current Circuit Breaker With Overcurrent Protection) General RCBO circuit breaker is applicable to electric circuits with rated voltage 230VAC, frequency 50/60Hz and rated current up to 40Amp. The RCBO provides indirect protection to the operator s body under such situation that the exposed live parts should be connected to a proper earth pole, RCBO also provides overcurrent protection to circuits in household,commercial and other similar installations. Moreover, it prevents potential fire danger caused by earth faullt current in case overcurrent protection device fails. Special tips: 1. RCBO circuit breaker with rated sensitivity up to 30mA could be used as supplementary protecting device in case other protecting device fails its protection against electric shock. 2. RCBO breaker designed for householf installation and other similar application,is for non-professional operation,and no maintenance is required. 3. RCBO breaker provides no protection against electric shock ersulted from direct contacts of both protected lines,or leakage current between these two lines. 4. Particular devices such as surge protective devices,surge arrester etc are recommended to install at upstream line to RCBO as precaution against potential against potential surge voltage and current occuring at its power input side. 5. Satisfying conditions and applications as mentioned above,RCCB with ON-OFF indicating device is considered suitable for isolation function. 6. RCBO overcurrent protection value is fixed and is not subject to further adjustment. Functions Switching and isolation function Protetion against overload and short-circuit currents Protection against the effects of sinusoidal alternating earth fault currents Protection against indirect contacts and additional protection against fire hazard caused by insulation faults Used in residential building Technical specifications Standard:IEC61009-1 Approvals:CB,CE,VDE(applying) Type(wave form of the earth leakage sensed):AC,A Rated current In(A):6,10,16,20,25,32,40 Number of poles:1P+N Rated voltage Ue(AC):230V Rated insulation voltage(AC):500V Rated frequency(Hz):50/60 Rated residual currents I n(mA):30,100,300 Rated breaking capacity acc.to IEC 61009 ultimate Icn(KA):6 Rated impulse withstand voltage(1.2/50)Uimp(kV):8 Dielectric test voltage at ind.freq.for 1 min.(kV):2.5 Surge current resistance(wave 8/20)(A):3000 Tripping characteristic:B,C Characteristic curve B(In):3-5 Characteristic curve C(In):5-10 Electrical life(0-C):4000 Mechanical life(0-C):10000 Degree of protection:IP40(top),IP20(termina),with connected conductors Mounting position:any Conductor cross-sections Terminal could use for busbar connection thickness(mm):0.8-2, Wiring(mm^2):1-25 Terminals Terminal tightening torque(N.m):2.5-3 The relatative humidity is max95% when ambient temperature(鈩冿級锛?5 Storage temperature(鈩冿級锛?40-+70 Altitude Max.(meters):2000ChinaCircuitBreakerFactory website:http://www.ilead-times.com/circuit-breaker/

Products Description 聽 聽 What is a frameless solar panel? 聽 The Frameless solar panel does not have any frame attached to them which results in lower embodied energy and retain its energy efficiency ratings. These frames have solar cells arrayed between two layers of glass and hence also called as glass-on-glass panels or dual glass panel. 聽 聽 聽 What are the disadvantages of transparent solar panels? 聽 鉁盩ransparent solar panels can only produce less amount of power so you will be needing to buy a large set of solar cells to power up entire your house. 鉁盩ransparent solar panels won't be able to power up the existing electronic accessories in your house. 聽 Which of the 3 main types of solar panels are the most efficient? 聽 Among all panel types, crystalline solar panels have the highest efficiency. Monocrystalline panels have an efficiency rating over 20%. PERC panels add an extra 5% efficiency thanks to their passivation layer. Polycrystalline panels hover somewhere between 15-17%. 聽 Bifacial Technology 聽 The power generation gain of the Bifacial Solar Panel mainly comes from the back side, and by receiving the reflected light from the atmosphere and the reflected light on the ground, the overall power generation of the bifacial module is increased. When the sun shines on the Bifacial Solar Panel, some of the light is reflected by the surrounding environment to the back of the panel. This part of the power can be absorbed by the battery, improving panels efficiency. 聽 聽 聽 聽 Standard solar module absorb direct light Bifacial solar module absorb direct light, ground reflected light, spatially scattered light 聽 聽 聽 Double-sided generation, powerfully energy boost: 聽 Fully utilizing the reflection and scattering of light, applying to highly reflective scenes such as water, sand, grass and white painted ground. With various types of brackets, more power is obtained, under lower kilowatt-hour costs. 聽 High reliability: Bifacial modules demonstrate superior long-term reliability, higher quality, and create more value. 聽 Products Data 聽 ModuleBSM380M-72BBSM390M-72BBSM400M-72B Reted Power(Pmpp) (W)380390400 Power Output Tolerance (W)0~+5 Rated Current (lmpp) (A)9.529.729.92 Rated Voltage (Vmpp) (V)39.9240.1340.33 Short Circuit Current (Isc) (A)9.839.949.99 Open Circuit Voltage (Voc) (V)48.6148.8849.08 Efficiency (%)19.419.9220.43 Operational Temperature-40~+85鈩?/p> Maximum Static Load5400Pa Maximum Wind Load2400Pa Maximum System VoltageIEC:1000/1500V Maximum Series Fuse Rating20A 聽 Production Show 聽 聽 Packing & Delivery 聽 Package White angle cover+corrugated case Wood pallet+packaging tapes 聽 Delivery 聽 Few quantity by express(DHL, UPS, FedEx, TNT) Batch order by air or sea(LCL/FCL) 聽 聽 Our Project 聽 聽 Certifications 聽 聽 Our Company 聽 聽 FAQ 聽 Q1: What are your main products?
