Product Positioning

The 3RM1002-1AA04 is a direct-start hybrid starter from the SIRIUS 3RM1 standard series. It uses screw terminal wiring and has a current range of 0.4-2.0A. It is one of the direct-start models with the smallest current specification in this batch and is suitable for small three-phase motor control.

Core Product Advantages and Features
Precision current protection
The current range is adjustable from 0.4 to 2.0A, suitable for small motors and providing precise overload protection settings.
Hybrid switching technology
At startup, it uses semiconductor contactless switching to reduce wear and tear, and after stable operation, it automatically switches to relay contacts to reduce heat generation and energy consumption.
Simplified 22.5mm body
It integrates start-up, protection, and switching functions into a single device, mounted on a 35mm DIN rail, saving control panel space.
Built-in electronic overload protection
It eliminates the need for an independent overload protection relay, simplifies wiring, and reduces the number of system components.
