Product Positioning

The 3RT2015-1JB41 is the standard screw-terminal model for the DC24V coil in the SIRIUS S00 frame contactor. It can be directly driven by a PLC output module or a 24V DC power supply, eliminating the cost and space required for an external relay. Screw terminals are suitable for applications requiring greater wire diameter flexibility or regular disassembly and maintenance. Both the main and auxiliary circuits maintain the same locking method as other contactors in the series. It has a built-in normally open auxiliary contact, which can be used for motor operation status feedback or interlocking control signals, making it a common replacement and addition option in general control panels.

Core Product Advantages and Features

DC24V coil

It can be directly driven by the PLC output point or a 24V DC power supply, simplifying the configuration of the control circuit.

1NO Normally Open Auxiliary Contact

It provides operation signal feedback function, which facilitates integration with PLC or indicator light circuits.

Screw terminal wiring

It has stable contact pressure and is suitable for applications with large variations in wire diameter or where frequent maintenance and replacement are required.

S00 Small Frame

It is compact in size and occupies little panel space, making it suitable for densely configuring multiple contactors.

30,000,000 mechanical lifespan

It can maintain stable switching characteristics even with frequent opening and closing over a long period of time.
