Siemens SIRIUS 3RT2325-1BW40 Contactor: Reliable 4-Pole Switching for Industrial Application

The Siemens 3RT2325-1BW40 is a high-performance 4-pole contactor from the SIRIUS 3RT23 series, engineered for switching weak or non-inductive loads (AC-1) up to 35 A at 400 V / 40 °C. Featuring a 48 V DC operating coil and integrated 1 NO + 1 NC auxiliary contacts, this size S0 contactor provides a robust and efficient solution for diverse industrial control systems.

Key Features & Benefit

• Robust Performance: Rated for 35 A (AC-1) at 400 V / 40 °C, suitable for demanding applications involving resistive loads.
• 4-Pole Configuration: Ideal for switching multi-phase circuits or applications requiring additional poles for control or isolation.
• 48 V DC Coil: Ensures reliable operation in DC control systems, offering consistent performance.
• Integrated Auxiliary Contacts: Comes with 1 normally open (NO) and 1 normally closed (NC) auxiliary contact, simplifying wiring and providing essential feedback for control circuits.
• Screw Terminals: Provides secure and straightforward electrical connections for both main and auxiliary circuits.
• Compact Size S0: Space-efficient design allows for flexible installation in control panels.
• High Contact Reliability: Engineered to maintain high contact reliability, even for switching low voltages (≤ 110 V) and currents (≤ 100 mA), making it suitable for solid-state circuits.
• Compliance & Standards: Adheres to international standards including IEC 60947-1, IEC 60947-4-1, and IEC 60947-5-1 (for auxiliary switches), ensuring safety and compatibility.
• Protection Features: Designed to be protected against short circuits, overload, and overvoltage when used with appropriate protective devices (e.g., fuses, circuit breakers, surge suppressors).
• Versatile Mounting: Supports screw and snap-on mounting onto a 35 mm standard mounting rail (DIN EN 60715).
• Expandable Design: Can be easily expanded with additional auxiliary switches from the SIRIUS accessories range for increased functionality.
• Wide Operating Temperature: Functions reliably in ambient temperatures from -25 °C to +60 °C.

Application

The Siemens 3RT2325-1BW40 contactor is an excellent choice for:

• Four-pole switching of weak or non-inductive loads (AC-1).
• Disconnecting loads or power generation plants from the grid.
• Transfer switching applications.
• General industrial control circuits where reliable switching of AC-1 loads is required.

Part of the modular SIRIUS system, this contactor offers seamless integration with other Siemens components like 3RU2 thermal overload relays or 3RB3 electronic overload relays for comprehensive motor protection. Its robust construction and adherence to global standards make it a dependable component for a wide range of automation and control task.
