3RT2518-2BM40

Description

Overview

The Siemens 3RT2518-2BM40 is a high-performance power contactor designed for reliable motor control and switching applications in industrial environments. Engineered under the Siemens SIRIUS series, this compact S00-size contactor delivers long operational life, superior electrical endurance, and outstanding switching capability for motors up to 7.5 kW at 400 V.

Equipped with 2 NO + 2 NC main contacts and a 220 V DC control voltage, this contactor ensures efficient integration into control panels, automation systems, and machinery with strict reliability requirements. Its spring-loaded terminals allow quick, secure, and maintenance-free wiring.

Function and Application

This contactor is primarily used for switching resistive loads (AC-1), but its design allows for use in AC-3 motor applications up to 7.5 kW. It is ideal for:

• Controlling non-motor loads such as heating elements, lighting systems, and capacitors.

• Interfacing with DC control circuits (220V DC coil) in complex automation systems.

• Use as a reversing contactor or for other switching duties requiring 4 main poles.

• Integration into compact control panels due to its small S00 frame size.

Benefit

1. Fast & Reliable Wiring: The innovative spring-loaded terminal technology cuts down on installation time and provides a secure, vibration-proof connection without the need for periodic retightening.

2. Versatile 4-Pole Design: Equipped with 2NO + 2NC main contacts, offering flexibility for switching complex loads or for use in applications where both breaking and making different circuits is required.

3. Space-Saving Footprint: The compact S00 size minimizes the required mounting space in cabinets, maximizing panel density.

4. DC Control Compatibility: The 220V DC coil is perfectly suited for common DC control systems in industrial automation, ensuring reliable operation.

5. SIRIUS Quality: As part of the Siemens SIRIUS line, this contactor offers exceptional longevity and operational reliability for reduced maintenance and downtime.
