Product Positioning

The 3RT2015-1AB02 coil voltage is reduced to 24V AC (50/60Hz), which is a low-voltage control design commonly used in control box circuits powered by step-down transformers and with high personnel safety requirements. The auxiliary contacts are a single set of normally closed (NC) contacts, suitable for direct connection to interlocking protection or safety monitoring circuits. The main circuit maintains the same level as the SIRIUS 3RT2015 series: AC-3, 7A/3kW at 400V; AC-1, up to 18A. The S00 is compact in size and uses screw terminal wiring, making it suitable for control panel designs with high safety requirements.

Core Product Advantages and Features

24V AC low-voltage coil enhances operational safety.

The 24V control circuit powered by a step-down transformer can reduce the risk of electric shock during operation and maintenance.

Built-in 1 set of normally closed (NC) auxiliary contacts

Suitable for integration into interlocking protection or safety monitoring circuits to enhance the system's ability to prevent malfunctions.

7A/3kW main circuit capacity

The AC-3 has a rated current of 7A and a power output of 3kW at 400V, while the AC-1 can reach 18A. Both are suitable for general small three-phase motors.

S00 minimum form factor, screw terminal wiring

With a size of only 57.5×45×73mm, it is easy to install in a control panel where safety is a priority.
