Product Positioning

The 3RM1302-3AA04 is the smallest current specification forward and reverse safety model in the Siemens SIRIUS 3RM1 hybrid motor starter, suitable for forward and reverse control and safe power-off requirements of small power motors below 0.75kW.

Core Product Advantages and Features

forward and reverse integrated

A single 22.5mm wide housing supports both forward and reverse rotation, eliminating the need for an additional reverse contactor.

Built-in safety power-off function

It features safety-related power-off design and meets SIL2 level according to IEC 61508 specifications.

Electronic overload protection

The CLASS 10A trip and adjustable current limit eliminate the need for a separate overload relay.

High short-circuit breaking capacity

According to UL489/CSA, the short-circuit breaking capacity is up to 60kA at 480V, with one set of SPDT auxiliary contacts.

Push-in control terminal

The control circuit uses spring-inserted terminals, while the main circuit maintains screw terminal wiring.
