Allen Bradley 电机保护断路器, 14.5 → 20 A, 480 V

使用 Allen Bradley 的 140M 系列电动机保护断路器，体验控制系统的卓越性能和出众的保护。Bulletin 140M MPCB 提供断开方式，用于电动机分支电路，分支电路和短路磁保护，过载热保护和手动切换。额定电流为 0.1...45 A这些多用途装置提供高切换容量和高电流限制，以确保您获得安全，可靠和流线型电动机控制过程。

140M 多路印刷电路板专门设计用于与 Allen Bradley 100-C 接触器系列一起使用，以提供 2 型协调，而不会过大接触器，额定功率高达 22kW。 这可确保起动器更经济。该断路器可根据个人要求进行定制。

这些装置是用于较小尺寸应用的经济型选择，可在更少空间内提供增强功能。使用 140M 时，无需电流限制器或备用熔丝，它们可安装在更靠近电源变压器的位置。由于这些 MPCB 的尺寸紧凑，您可以节省面板空间，并受益于更高效的控制柜。它们可通过 DIN 导轨轻松安装和安装。

为实现轻松，自动的 2 型协调，可根据额定电机电流选择断路器和接触器 - 无需进行复杂计算。140M 装置包括 " 开 " ， " 关 " 和 " 跳闸 " 指示，可锁定在关闭位置。它们具有环境温度补偿： -20 至 +60°C

•行程等级 10
•失相保护

UL Listed Application Ratings:

UL 508 - Manual Motor Controller
UL 508 Manual Self-Protected (Type E) Combination Motor Controller

An MPCB is a safety measure device which is used for controlling electric motors and protecting them from faults such as overloads and short circuits, which can cause serious damage to the motor. They work by interrupting the circuit when abnormal conditions are detected and instantly switching off the motor. The three main functions of an MCPB are thermal protection, magnetic protection, and phase protection. They can also turn a motor off and on manually. They are a cost-efficient and reliable type of motor protection technology and offer a low reset time, which minimises operational downtime. They are available in many different sizes and settings, making them a versatile option.

Rockwell Automation is a global leader in industrial automation and digital transformation, and brings smart manufacturing to life. With a long legacy of creating Allen-Bradley® integrated control and information solutions, we help make you as productive as possible. Our portfolio of sensing, safety and motor control products can support your move towards smart machine applications. Allen-Bradley® IO-Link sensors are data-enabled and communicate with all field buses, providing diagnostic and health information about the device before a machine stops, and enabling quick production changeovers through fast parameter downloads from PLCs into the device. This reduces machine downtime and increases manufacturing OEE. For safety components, products with built-in diagnostics simplify the set-up of the smart device, and reduce maintenance, leading to a more efficient, machine data-driven approach.
