Siemens 3RT2015-1BP41 SIRIUS Power Contactor, 7A, 3kW, 230V DC Original Brand New

Overview

The Siemens 3RT2015-1BP41 is a high-performance SIRIUS 3RT2 power contactor designed for reliably switching motors and other resistive loads in industrial control systems. As part of the SIRIUS Innovations portfolio, this 3-pole contactor is engineered for a long service life, high contact reliability, and a compact design (Size S00). It features a powerful $230\text{ V DC}$ operating coil and secure screw terminal connections for the main and auxiliary circuits.

Benefit & Application

• Compact Design: The small Size S00 makes it ideal for use in space-constrained control panels and cabinets.
• DC Coil Efficiency: The $230\text{ V DC}$ coil offers low power consumption for efficient operation and reduced heat generation.
• High Reliability: Part of the trusted Siemens SIRIUS 3RT2 range, ensuring dependable operation for motor switching applications.
• Versatile Connection: Features robust screw terminal connections for easy and secure wiring of the main and auxiliary circuits.
• Integrated Auxiliary Contact: The built-in $1\text{ NO}$ auxiliary contact simplifies wiring for control and signaling circuits.

Function

The Siemens 3RT2015-1BP41 contactor acts as an electrically controlled switch, primarily used for:

1. Motor Switching: Safely and reliably switching ON and OFF 3-phase AC motors up to $3\text{ kW}$ at $400\text{ V}$.
2. Load Control: Controlling resistive and highly inductive loads (AC-3e/AC-3 operational class).
3. Automation Integration: Interfacing between control signals (e.g., from a PLC using the $230\text{ V DC}$ coil) and the main power circuit.

Technical Features

• AC-3e/AC-3 Rating: Suitable for standard motor operation (switching squirrel-cage motors).
• High Durability: Mechanical life and electrical life designed for demanding industrial environments.
• Easy Installation: Mounts quickly on a DIN rail or via screw-fit.
• Compatibility: Fully compatible with a wide range of SIRIUS 3RU2 thermal overload relays and other 3RT2 accessories (auxiliary switch blocks, surge suppressors, etc.) to build complete motor starters.
