DC Circuit Breaker MCB 1000V Manufacturer for Solar PV Systems

DC Circuit Breaker DC 1000V 4P 16A-63A DIN Rail Circuit Breaker Thermal-Magnetic Trip, Low Voltage,Protector for Solar PVDC Circuit  Breaker (MCB)DesciptionDC Circuit Breaker  PV DC breaker supplementary protectors are  designed to provide overcurrent protection within  appliances or electrical equipment, where a branch circuit  protection is already provided or not required. Devices  are designed for direct current (DC) control circuit  applications. A User can use the YRL7-63DC circuit breaker for DC rated voltage to 1000V, rated current to 63A line, for overload and short circuit protectionRated Current: 16A-63AOperating voltage (Ue): 1000V DCImpulse Voltage (Uimp): 4kVNumber of Pole: 2PTrip method: Thermal-Magnetic tripIcu=6kAFeature1.The state-of-art design: Elegant appearance; cover and handle in arc shape make comfortable operation. Contact position indicating window Transparent cover designed to carry label.2.Handle central-staying function for circuit fault indicating: In case of overload, to protected circuit, maniature circuit breaker handle trips and stays at central position, which enables a quick solution to the faulty line. The handle cannot stay in such position when operatedmanually.3.High short-circuit capacity: High short-circuit capacity 10KA for whole range and 15kA capacity for current rating up to 40A thanks to the powerful electric arc extinguishing system. Long electrical endurance up to 6000 cycles thanks to quick making mechanism.4.Handle padlock device: MCB handle can be locked either at “ON” position or at “OFF” position to prevent unwanted operation of the product.5.Screw terminal lock device: The lock device prevents unwanted or casual dismounting of connected terminals.6. 4P DIN Rail Circuit Breaker Thermal-Magnetic Trip, Low Voltage,Protector for Solar PVTechnical data DC Circuit BreakerOperating Voltage (Ue)2P=550V DC 4P=1000 V DCRated insulation voltage (Ui)12V-1200 VDCBreaking capacity (Icu)10 kAImpulse voltage (Uimp)6 kAElectrical connectionBy the bottom for In and OutNumber of poles1P, 2P, 3P, 4PStandardsIEC 60947-2 EN 60947-2 SAA CE TUVRated service breaking capacity (Ics)100 % of the IcuEndurance (O-C)Electrical1,500 cycles (where L/R=2 ms)Mechanical20, 000 cyclesMechanical20, 000 cyclesDegree of pollution2CategoryA (no delay in accordance with IEC / EN 60947-2 standards)Degree of protection (IEC 60529)IP40TropicalisationRelative humidity: 95 % at 55°C in accordance with IEC 60068-2 and GB 14048.2 standardsTemperatureOperating-25°C to 70 °CStorage-40°C to 85°CDimension miniature circuit breakerApplication The JL7-63 is a DC circuit breaker dedicated to multi string photovoltaic installations.This circuit breaker is designed to protect the cables located between each string of photovoltaic modules and the photovoltaic inverter against overloads and short circuits (see application diagram).Combined with a switch , the JL7-63 will be installed in a string PV protection enclosure at the end of each string of photovoltaic modules. It can be locked (by a padlocking device) in OFF position as a safety measure for  removal of the PV inverter.Since a fault current can flow in the reverse direction to the operating current, the JL7-63 can detect and protect against any bidirectional current.To ensure the safety of the installation, it is necessary, depending on the various types of application, to combine the JL7-63 with: a residual current device at the AC end a fault passage detector (insulation monitoring device) at the DC end an earth protection circuit breaker at the DC end.In all cases, fast action on site will be required to clear the fault (protection not ensured in the event of a double fault).JL7-63 is not polarity sensitive: ( ) and (-) wires can inversed without any risk.The JL7-63 is: delivered with three inter-pole barrier to provide increased isolation distance between two adjacent connectors.ln Compliance With IEC/EN606947-2The IEC 606947-2:2016 is an international standard that applies to all circuit breakers in which professionals propose the primary contacts to connect them to circuits. The rated voltage should not exceed a thousand volts alternate current or one thousand five hundred volts’ direct current. This international standard also contains additional requirements for integrally fused circuit-breakers.SUNENG® AdvantageSUNENG®  is specialized in Photovoltaic Cable and Solar accessories (SPD & MCB) since 2004.
