Earth Leakage Circuit Breaker 3kv

Application scope The products products provide protection against earth faults, overloads, short circuits and over -voltage incommercial and dometic installation. The PCBO with both disconnected neutral and phase guarantees its proper actuation against eath leakage fults even when the neutral and phase are wrongly connected the electronic RCBO incorporate a filtering device preventing the risks of unwanted due to transient voltages and transient currents, positive contact indication in accordance with 16th edition of the IEE wiring regulations. Main technical parameters Type: DNLE-32 Numbers of poles: 1P+N Rate current: 6.10.16.20.25.32 A Rate operating current: 10.30.100.300. MA Rated current: AC240V Residual operating current scope: 0.5In-In Residual current off-time: ≤ 0.3s Ultimate short-circuit breaking capacity(Inc) Endurance: ≥ 6000 times Terminal protection: IP20 Construction features 1. Measuring component and buckling component of products is located between enter line end and entrance line end; 2. Movement characteristic of products can not be changed with outside mechanical tool; 3. The operating organization has the free function to take off and buckle; 4. Operate part can not be taken down from the shell outer of products, the shell can not influence the operating organization to work, the accessory group which replace the feelers pressure, should guarantee the feelers pressure does not change while running. Normal Opeation Conditions 1. Location: Installation location can not exceed 2000 meters above sea level. 2. Air conditions: Relative humidity in the installation place can not exceed 50%when the air reaches the highest temperature +40° C, the average minmum temperature when it is the wettest can not exceed 25° C, Relative humidity not exceeding 90%. 3. Installation Conditions: Installation is divided into grade II, grade III 4. Installation Pollution Grade: Installation pollution grade is grade II. 5. Installation Conditions: Magnetic field outside the installation place can not exceed 5times of the site of terrestrial magnetism in all direction. Normally speaking, RCBO should be mounted vertically. If the operation handle puts through power source upward, there should be no notable impact and vibration in the installation place. Notice 1. Leakage Protection function of RCBO is tested and adjusted by the manufacture, users can not open the products at random during usage. 2. After using RCBO for a certain time (normally one month), test button should be pressed once in a state of making the circuit to check whether the function of RCBO is normal and reliable (press test button once, the RCBO can break off once ). If abnormal, it should be unloaded and sent to the manufacturer for repair. 3. RCBO must not be wetted or soaked by rain, snow or water during the course of transportation, storage and usage.
