3RT2015-1VB41

The 3RT2015-1VB41 is a Siemens SIRIUS S00 miniature 3-pole contactor. It uses a DC24V coil with screw terminals, ensuring secure wiring and making it suitable for applications requiring frequent wire replacement. The main contacts are AC-3 rated at 7A, 3kW/400V, and it comes with one set of normally open auxiliary contacts. It is commonly used in control circuits where PLC outputs are directly driven.

Product Positioning

The 3RT2015-1VB41 is a screw-terminal version of the Siemens SIRIUS S00 frame contactor with a DC 24V coil. The coil can be directly driven by a PLC output module or a 24V DC power supply, eliminating the need for an additional relay. While screw terminals are not as fast as spring terminals, they offer stable contact pressure and are suitable for applications requiring regular disassembly and maintenance or where wire diameter selection is flexible. It includes a built-in normally open auxiliary contact to provide operational status feedback signals to the upper control system.

Core Product Advantages and Features

DC24V coil

The coil can be directly driven by the PLC output point or a 24V DC power supply, simplifying the control circuit design.

Screw terminal wiring

Both the main circuit and the auxiliary circuit use traditional screw-locked terminals, ensuring secure wiring and facilitating on-site maintenance.

1NO auxiliary contact

It has a built-in set of normally open contacts, which can be used to feed back operating signals or for interlock protection.

S00 Standard Framework

It shares the same external dimensions as screw terminal contactors in the same series, which facilitates spare parts interchange and management.

High mechanical durability

With a mechanical life of approximately 30 million cycles, it is suitable for the frequent start-up and shut-down requirements of continuous production equipment.
