CE55NN3A反向接触器相关信息

产品概述

CE55NN3A反向接触器是一种工业用途的交流接触器，主要用于控制电动机和其他电气设备的正反转操作。其主要功能是通过改变电路中的电流方向来实现设备的反向运转，广泛应用于工业自动化、冶金、造纸、矿山、石化等多个领域。

工作原理

反向接触器的工作原理基于电磁吸合作用。当线圈通电时，产生的磁场吸引触头闭合，从而实现电路的连接；当线圈断电时，触头在弹簧力的作用下分离，切断电路。通过控制线圈的通断，可以实现电路的正向或反向连接。

应用场景

CE55NN3A反向接触器广泛应用于以下场景：

电动机控制：用于控制电动机的正反转，实现机械设备的正反转操作。

自动化生产线：在自动化生产线上，通过控制电动机的正反转，可以实现工件的自动翻转和输送。

冶金行业：在冶金行业中，反向接触器用于控制轧机的正反转，提高生产效率。

造纸行业：在造纸行业中，反向接触器用于控制卷纸机的正反转，实现纸张的自动卷取。

CE55NN3A reverse contactor related information

Product overview

The CE55NN3A reverse contactor is an AC contactor for industrial use, mainly used to control the forward and reverse operations of motors and other electrical equipment. Its main function is to realize the reverse operation of the equipment by changing the direction of current in the circuit. It is widely used in industrial automation, metallurgy, papermaking, mining, petrochemical and other fields.

Working principle

The working principle of the reverse contactor is based on electromagnetic attraction. When the coil is energized, the generated magnetic field attracts the contacts to close, thereby connecting the circuit; when the coil is deenergized, the contacts separate under the action of the spring force, cutting off the circuit. By controlling the on and off of the coil, the forward or reverse connection of the circuit can be achieved.

Application scenarios

CE55NN3A reverse contactor is widely used in the following scenarios:

Motor control: used to control the forward and reverse rotation of the motor to achieve forward and reverse rotation of mechanical equipment.

Automated production line: In an automated production line, by controlling the forward and reverse rotation of the motor, the workpiece can be automatically turned over and transported.

Metallurgical industry: In the metallurgical industry, reverse contactors are used to control the forward and reverse rotation of rolling mills to improve production efficiency.

Papermaking industry: In the papermaking industry, the reverse contactor is used to control the forward and reverse rotation of the paper winding machine to realize automatic winding of paper.

Technical parameters

Rated voltage and current

Rated voltage: 24V to 220V, depending on application requirements.

Rated current: It varies according to the specific model and application scenarios. Common ones are 60A, 100A, etc.

Number of poles and contact form

Number of poles: Generally 3 poles or 4 poles, suitable for different electrical control needs.

Contact form: The number of normally open main contacts and normally closed auxiliary contacts varies depending on the model, and is usually equipped with a variety of contact configurations to meet different circuit connection needs.

Working environment temperature and altitude

Working environment temperature: usually between -20°C and 50°C, some models can adapt to higher temperature environments.

Working altitude: Generally it can be used in environments below 1,000 meters above sea level.
