Siemens 3RT2325-1BM40 Contactor 4-Pole, 35A, 220V DC, Size S0 Brand New

Overview

The Siemens 3RT2325-1BM40 is a high-performance 4-pole contactor designed for efficient switching of weak or non-inductive loads (AC-1). This robust device is a key component for various industrial applications, including power generation plants, transfer switching, and general load disconnection. With a rated current of 35A at 400V / 40°C, a 220V DC control voltage, and a compact Size S0 frame, it offers reliable and space-saving solutions. The integrated 1 normally open (NO) and 1 normally closed (NC) auxiliary contacts, along with secure screw terminals, ensure versatile and dependable operation.

Key Features and Benefits

• High Performance (AC-1): The contactor is specifically designed for switching non-inductive or low-inductive loads, making it ideal for applications like resistive heating, lighting, and power distribution circuits.
• 4-Pole Design: This configuration allows for the simultaneous switching of four separate circuits, providing enhanced control and safety in complex systems.
• Robust Construction: Built to withstand demanding industrial environments, the contactor adheres to strict international standards, including IEC 60947-1, IEC 60947-4-1, and IEC 60947-5-1.
• Integrated Auxiliary Contacts: The built-in 1 NO and 1 NC auxiliary contacts provide immediate feedback on the contactor’s status, simplifying circuit design and control logic.
• Versatile Control: The 220V DC operating mechanism ensures reliable performance and compatibility with a wide range of control systems.
• Easy and Secure Installation: The screw terminals provide a simple and robust connection for main and auxiliary circuits, ensuring a secure and long-lasting electrical connection.
• Compact Size S0: The small footprint of the Size S0 frame allows for high-density mounting in control panels, optimizing space and reducing overall panel size.

Function

• Load Switching: Efficiently connects and disconnects non-inductive or low-inductive loads from the power supply.
• Control Integration: The auxiliary contacts can be used for interlocking, signaling, or to trigger other components in a control circuit.
• Safety Disconnection: Enables the safe isolation of equipment from the power grid.
• Transfer Switching: Can be used in conjunction with other contactors or relays to switch between different power sources.

Protection and Standard

The Siemens 3RT2325-1BM40 contactor is engineered with a focus on safety and reliability. While it must be protected against short circuits and overloads with suitable external measures, it is designed for a high degree of electromagnetic compatibility (EMC) in environment category A. Surge suppressors (RC elements, varistors, etc.) can be added to the coil circuit as accessories to protect against overvoltage.

Application

• Commercial and industrial lighting systems
• Heating, ventilation, and air conditioning (HVAC) systems
• Control panel and motor control center (MCC) applications
• Power distribution panels
• Switching resistive loads
• Power generation and grid connection systems
