The mechanical life of Chint CJX2-5011 AC contactor is 10 millones de veces (es decir., 10 million operating cycles).
Detailed Explanation
The mechanical life of Chint CJX2-5011 AC contactor refers to the maximum number of contact closing and opening operations it can complete under no-load conditions. This parameter reflects the durability of the contactor’s mechanical structure and is a key indicator for evaluating its service life.
According to Chint’s official product data and authoritative electrical product databases, the mechanical life parameters of CJX2 series contactors are shown in the table below:
| Model Range | Vida mecánica (10,000 ciclos) |
| CJX2-09~32 | 1000 |
| CJX2-40~65 | 1000 |
| CJX2-80~95 | 800 |
CJX2-5011 falls into the CJX2-40~65 model range, so its mechanical life is 10 millones de veces.
Supplementary Relevant Parameters
In addition to mechanical life, other key technical parameters of CJX2-5011 are as follows:
Vida eléctrica (under AC-3 application category): 600,000 ciclos
Corriente nominal: 50A (under AC-3 application category at 380V)
Contactos auxiliares: 1 set of Normally Open (NO) + 1 set of Normally Closed (CAROLINA DEL NORTE) (indicated by the suffix “11” in the model)
Frecuencia de funcionamiento: 1,200 operations per hour
Application Significance
A mechanical life of 10 million times means that even in an industrial environment with frequent operations (p.ej., 1,000 operations per day), this contactor can theoretically be used for approximately 27 years without mechanical failures, which is an important reflection of its high reliability.
