Siemens 3RT2518-2BB40 Power Contactor 16A, 7.5kW, 4-Pole, 24V DC Original Brand New

Overview

The Siemens 3RT2518-2BB40 is a high-quality power contactor designed for efficient switching and protection in industrial electrical systems. With an AC-3 rating of 16 A and 7.5 kW / 400 V capacity, this 4-pole contactor ensures smooth operation for motors and other electrical equipment. Its 24 V DC coil and versatile configuration of 2 NO + 2 NC main contacts offer flexibility for a wide range of control applications. The spring-loaded terminal design guarantees secure and reliable connections, making it ideal for modern industrial setups.

Key Benefit

• Reliable Switching: AC-3 rated for 16 A, 7.5 kW / 400 V, perfect for motor control.

• Flexible Configuration: 2 NO + 2 NC main contacts for versatile applications.

• Secure Connections: Spring-loaded terminals reduce wiring errors and improve reliability.

• Compact & Efficient: Size S00 allows for space-saving installations.

• Industrial-Grade Quality: Built by Siemens for long-lasting performance in demanding environments.

Function and Application

The Siemens 3RT2518-2BB40 functions as an electrically operated switch, designed primarily for switching motors (AC-3 duty) and resistive loads. Its 4-pole design makes it suitable for switching three-phase loads with a neutral conductor, or for controlling two independent single-phase circuits simultaneously.

Application

• Motor Control: Switching small to medium-sized motors up to 7.5 kW.

• Reversing Circuits: Used in conjunction with a second contactor for reversing the direction of three-phase motors.

• Heating and Lighting: Controlling high-power heating elements, lighting systems, and solenoid valves.

• Industrial Machinery: Integration into control panels for pumps, compressors, conveyors, and machine tools.
