Overview
Sirius 3RK43 MCU汽车入门家族的投资组合
The SIRIUS MCU motor starter family (MCU = Motor Control
Unit) rounds off the bottom end of the SIRIUS motor starter
range.
这一系列的电动机启动器高度保护是
system solution for the cabinet-free controlling of AC loads in the
field.
MCU产品范围从I/O控制电动机延伸

供汽车起动器
在现场，高度保护）
The MCU motor starters are completely pre-wired inside, have a
high degree of protection and are designed for switching and
protecting any AC loads. They are mostly used on standard
three-phase motors in direct or reversing duty up to 5.5 kW at
400/500 V AC (electromechanical switching) and 400/460 V AC
（电子开关）。
MCUS集成的电动机和短路保护
consists either of an electromechanical controlgear assembly or
solid-state overload protection and a motor starter protector unit
for short-circuit protection.
MCUs with metal enclosure are designed for the switching of
three-phase motors. Integrated control of the electrically oper-

•
集成可锁的维修开关
•
Comprehensive motor protection thanks to integrated over-
load and short-circuit protection with SIRIUS 3RV motor starter
protectors or integrated solid-state overload relays (solid-state
starters)
•
Overload protection with thermal release (bimetal) or solid-
状态超载继电器具有广泛的设置
•

）
•
数字的强大且广泛使用的M12连接方法
inputs and outputs to connect I/O stations and the AS-i bus
connection increase flexibility and prevent errors in the system
configuration.
•
LED（用于AS-I巴士连接）可以提供全面
当场对设备的诊断。
•
Simple mounting for AS-i and external auxiliary voltage
（24 V DC）在M12连接上
•
Manual operation: An integrated key-operated switch "MAN-0-
自动”和一个用于打开的选择器按钮，关闭
and changing the direction of rotation for control purposes
during commissioning or maintenance

This motor starter version offers an economical solution for
controlling and monitoring conveyor belts, pumps, fans or com-
pressors.
On this MCU the control commands and the status queries are

In manual mode a selector button is used for switching on,
switching off and changing the direction of rotation.
The status/diagnostics LEDs fitted to the cover indicate the
current operating state of the motor starter.
