Application
Industries
3RB24电子超载继电器适合客户
来自所有想要保证最佳电流和的行业
依赖温度的电荷保护
(e.g. motors) under normal and heavy starting conditions
(CLASS 5E to 30E), minimize project completion times, invento-
雷和能耗，并优化植物的可用性和
维护管理。
Application
The 3RB24 electronic overload relays have been designed for
保护三相异步和单相
AC motors.
除了保护功能，这些设备还可以使用
与接触器一起作为直接或逆转起动器
(star-delta (wye-delta) start also possible), which are controlled
通过io-link。这使得可以直接控制驱动器
来自高级控制器或现场的IO链接通过可选
hand-held device and also, for example, to return current values
directly via IO-Link.
如果单相交流电动机将受到3RB24的保护
电子超载继电器，电流的主要电流路径
测量模块必须串联连接。

).
Ambient conditions
The devices are insensitive to external influences such as
冲击，腐蚀性环境，衰老和温度
波动。
In the temperature range from -25 °C to +60 °C, the
3RB24电子超载继电器补偿温度
根据IEC 60947-4-1。
配置注释，用于使用以下–25°C或更高的设备
+60°C on request.
