Kemus insists on a comprehensive quality assurance system, ensuring our products meet global standards for safety and reliability.
Product Description
Classification of CDW1 Air Circuit Breaker
1. Divided by installation mode: fixed, drawer type.
2. According to the mode of operation: electric operation, manual operation.
3. According to the type of release: with intelligent controller, undervoltage instantaneous (or delay) release and shunt release.
4. Air circuit breaker intelligent controller classification:
① ECW-L type (economy type, light column display)
② ECW-M type (ordinary type, LED digital display)
③ ECW-H type (Enhanced, LCD liquid crystal display)
CDW1 Air Circuit Breaker Grounding Fault Protection Classification
① One is to detect the neutral current, when the three-phase current is balanced, the neutral current is zero, when the three-phase current is unbalanced, the neutral current exceeds the setting value, the intelligent controller alarms, after the setting delay time, issue instructions as required, so that the air circuit breaker is disconnected or constantly open.
② The other is to detect the grounding line current, when the current exceeds the setting value, the intelligent controller alarms, after the setting delay time, as required to issue instructions, so that the air circuit breaker is disconnected or constantly open, grounding fault protection characteristics for a fixed time limit.
CDW1 Air Circuit Breaker ACB Structural Feature
The air circuit breaker is a three-dimensional layout form, which is mainly composed of contact system, intelligent controller, manual operation mechanism, electric operation mechanism, installation plate (fixed) or drawer (drawer type); It has the characteristics of compact structure and small volume. The contact system is enclosed in an insulated base plate.
Each pole contact is also separated by an insulating board to form a small chamber, and the intelligent controller, manual operation mechanism, and electric operation mechanism are in front of it to form their own independent units, such as one of the units is broken, it can be removed and replaced by a new one.
Operating Mechanism Of CDW1 Air Circuit Breaker
Air circuit breaker operation mode has two kinds of manual and electric, circuit breaker adopts spring storage energy closure, closing speed has nothing to do with electric or manual operation speed, circuit breaker uses CAM compression a set of springs to achieve the purpose of energy storage, and has free tripping function.
The circuit breaker has three operating positions, namely, energy storage, closing and breaking.
