◇Protection against the effects of earth leakage overload and short circuit currents. ◇2P switching of ph&N,Phase only protected against overloads and short circuits. ◇In commercial, industrial and domestic electrical distribution systems. ◇Note: It can’t be used as the sole means of providing protection against direct contact. ◇The RCBO incorporates a residual current operated electromagnetic release which operates without any auxiliary source of supply to open a circuit automatically in the case of an earth leakage fault between phase and earth greater than or equal to. ◇MCB & RCCB provides: ◇Protection against indirect contact. ◇Complementary protection against direct contact. ◇Protection for the installation against insulation faults.
Normal operation and mounting requirement
◇Circumstance temperature-5°C~+40°C,average temperature not exceeding 35°C. ◇Alitude above sea level less than 2000m. ◇Humidity not exceeding 50% at 40°C and not exceeding 90% at 25°C. ◇Installation class II or III. ◇Pollutioin class II. ◇Installation method DIN Rail mounting type. ◇The external magnetism shall not be more than 5 times of terrestrial one. ◇Product shall be installed vertically at the place where there shall be no severe impact and vibration. The product is switched on when the handle is at upper position.
◇Measuring component and buckling component of products is located between enter line end and entrance line end; ◇Movement characteristics of products can not be changed with outside mechanical tool; ◇The operating organization has the free function to take off and buckle; ◇Operate part can not be taken down from the shell outer of protects, 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.
