Product Positioning

The 3RA2315-8XE30-1BB4 belongs to the Siemens SIRIUS 3RA23 series forward and reverse combination contactor. It consists of two S00 size contactors with mechanical and electrical interlocks. It is designed for forward and reverse switching of three-phase motors, powered by a 24VDC coil, and is suitable for automated equipment such as conveyors and winches that require bidirectional operation.

Core Product Advantages and Features

Dual contactor interlock design

It has a built-in mechanical and electrical dual interlocking mechanism to prevent short circuits caused by the simultaneous operation of forward and reverse contactors, thus improving system safety.

S00 miniaturized design

It adopts the SIRIUS S00 size, with a compact size, making it suitable for use in control panel configurations with limited space.

Screw terminal wiring

Both the main circuit and the coil adopt a screw terminal design, making field wiring and maintenance more convenient and intuitive.

High durability mechanical life

The rated mechanical operating life reaches 10 million cycles, reducing the replacement frequency in frequent operation scenarios.
