| Product Application： | Suitable for AC 50Hz, rated insulation voltage 660V, rated working
voltage 380V (400V) and below, rated current up to 100A. Generally
used as a distribution. Under normal circumstances, the circuit
breaker can be converted, respectively, as the lines are not
frequent and infrequent start motor used. Distribution circuit breaker used in the distribution of electric energy distribution network, and can be used as circuits and equipment overload, short circuit and under voltage protection. Motor protection circuit breaker in the distribution network as a squirrel cage motor starting and breaking as well as motor overload, short circuit and under voltage protection. |
| Structural Features： | The Y-series circuit breaker is the basic product, the insulating
case, operating mechanism, contact system and the release of four
components. Circuit breaker operating mechanism to make contact
with the fast closing and breaking features, the "combined"
"Minute" "re-label" and "free trip" position to the handle position
to distinguish. J-and G-type circuit breaker is based on the Y-derived basic products designed by. J Y-type circuit breaker circuit breaker is to contact the structural improvement, so that in the short-circuit case, the agency action before the moving contact can quickly disconnect to achieve greater capacity for cutting purposes. G Y-type circuit breaker circuit breaker in the series after a floor consisting of parallel conductors repulsion limiting contact system, which the repulsive force than the J-type contact long distance off, therefore the limits more quickly flow; in the normally open circuit is closed and the release action for the protection of the whole range of circumstances, by the Y-type circuit breaker to complete. Once the big currents in the network or large short-circuit current, the series current limiting contact repulsion quickly denounced by the electric power to open, while limiting the introduction of the arc. Exclusion in the contact opening process, the circuit breaker trip unit can be operated institutions to make Y-breaking contacts. Repulsion limiting the contact is the reduction or disappearance of the current return to a closed state. Four-pole circuit breaker neutral pole (N) do not install release components, located in the far right position. In the analysis and synthesis process, the provisions of the neutral pole higher than the other three very close into the first contact points than the other three poles when the gate after the break. YGeneral type J— High-type G— The highest type |
