Product Description

The Siemens 3RT2015-1BB41 is a SIRIUS 3RT2 power contactor designed for switching three-phase motors and other industrial electrical loads. It is rated at 7 A under AC-3e/AC-3 utilization at 400 V and supports motor loads up to 3 kW at 400 V, with a 24 V DC control coil. The compact S00 contactor includes one normally open instantaneous auxiliary contact, screw-type terminals, and supports both 35 mm DIN-rail and screw mounting.

Standard Features

  • 7 A AC-3e/AC-3 Motor Switching: Rated for 7 A at 400 V under AC-3e and AC-3 utilization categories for three-phase motor switching applications.

  • 3 kW Motor Capacity: Supports three-phase motors rated up to 3 kW at 400 V under AC-3e/AC-3 conditions.

  • 24 V DC Control Coil: Uses a 24 V DC control supply with a specified coil operating range of 0.8 to 1.1 times the rated control voltage.

  • Integrated 1 NO Auxiliary Contact: Includes one instantaneous normally open auxiliary contact for control, signaling, and interlocking circuits.

  • Compact S00 Frame: The 45 mm wide S00 housing supports space-efficient installation in industrial control panels.

  • Flexible Panel Installation: Supports screw mounting or snap-on mounting to a 35 mm DIN rail, with screw-type terminals for main, auxiliary, and control circuits.

  • 30 Million Mechanical Operating Cycles: Siemens specifies a typical mechanical service life of 30,000,000 operating cycles for the contactor.
