Siemens SIRIUS 3RT2316-2BM40 Contactor, AC-1, 18A, 400V/220V DC, 4-Pole, Spring-Loaded, Size S00 Original Brand New

Overview

The Siemens SIRIUS 3RT2316-2BM40 is a high-performance 4-pole contactor designed for reliable switching of weak or non-inductive loads (AC-1) up to 18 A at 400 V / 40 °C. Featuring a 220 V DC spring-loaded terminal operating mechanism and a compact S00 size, this contactor offers excellent performance for a wide range of industrial applications.

Key Features & Benefit

• Robust Performance: Rated for AC-1 applications, ideal for resistive and non-inductive loads, disconnecting loads, or power generation plants from the grid, and transfer switching.
• Efficient Control: Equipped with a 220 V DC spring-loaded terminal operating mechanism for secure and reliable connections.
• Compact Design: Size S00 ensures space-saving installation in control panels and industrial enclosures.
• Integrated Auxiliary Contact: Includes one integrated auxiliary contact (NO) in the basic unit, with options for further expansion.
• High Reliability: Designed to meet demanding industrial standards, ensuring long-term operational stability.
• Standards Compliant: Fully compliant with IEC 60947-1, IEC 60947-4-1, and IEC 60947-5-1 (auxiliary switches) for global applicability and safety.

Comprehensive Protection & Integration

The Siemens 3RT2316-2BM40 is engineered with robust protection in mind:

• Short-Circuit & Overload Protection: Essential for main, auxiliary, and control circuit connections. Consult the technical product data sheet for specific protection requirements for free-standing contactors and device combinations (e.g., with overload relays or circuit breakers).
• Overvoltage Protection: Can be retrofitted with RC elements, varistors, diodes, or diode assemblies (ordered separately) for effective damping of opening surges in the coil, protecting your control circuits.
• Electromagnetic Compatibility (EMC): Fulfills requirements for environment category A, ensuring reliable operation in various industrial settings.

Versatile Connection Methods:

• Main Circuit: Features convenient spring-loaded terminals with a plug-in design for easy and secure wiring.
• Auxiliary & Control Circuit: Utilizes reliable screw terminals for flexible connection.

Seamless System Integration:

• Motor Protection: Compatible with Siemens 3RU2 thermal overload relays or 3RB3 electronic overload relays for comprehensive motor protection when used in conjunction with specific 3RT23 contactor versions (this 3RT2316-2BM40 is primarily for AC-1 loads, but this feature is relevant to the 3RT23 series).
• Auxiliary Contact Expansion: Expandable with additional auxiliary switches to meet diverse control requirements.
• Operating Mechanism: Features a conventional DC operating mechanism, ensuring precise control.
