Product Positioning

The 3RT2015-1HB42 is a screw-terminal version of the SIRIUS S00 frame contactor with a DC 24V coil. Its key feature is its wide operating temperature range of -25°C to 60°C, making it suitable for outdoor distribution boxes, non-air-conditioned workshops, or industrial environments with significant temperature variations, while maintaining stable operating characteristics. The main circuit specifications are consistent with other S00 frame screw-terminal contactors in the same series. It can be directly driven by PLC output or a 24V DC power supply and complies with international safety regulations such as IEC 60947-4-1 and IEC 60947-5-1, making it suitable for control panel designs that prioritize environmental tolerance.

Core Product Advantages and Features

Wide temperature tolerance range

With an operating temperature range of -25°C to 60°C, it is suitable for outdoor distribution boxes and industrial sites with large temperature differences.

DC24V coil

It can be directly driven by the PLC output point or a 24V DC power supply, reducing the need for additional relays.

Screw terminal wiring
