Siemens 3RT2325-1AP60 SIRIUS 3RT2 Power Contactor

Overview

The Siemens 3RT2325-1AP60 is a robust and reliable 4-pole power contactor from the SIRIUS 3RT2 series, specifically designed for switching non-inductive or weakly inductive loads (AC-1). With a rated operational current of 35 A at 400 V / 40 °C, this compact S0 size contactor is an ideal solution for various industrial control applications, including disconnecting loads, power generation plants from the grid, and transfer switching. Its versatile control coil supports 220 V AC at 50 Hz and 240 V AC at 60 Hz, ensuring broad compatibility. Equipped with 1 normally open (NO) and 1 normally closed (NC) auxiliary contact, along with secure screw terminals, the 3RT2325-1AP60 offers dependable performance and flexible integration into control panels.

Product Features & Benefits:

• High Performance AC-1 Switching: Rated for 35 A at 400 V / 40 °C, it excels in switching non-inductive or weakly inductive loads, ensuring efficient operation and longevity.
• Versatile 4-Pole Design: Ideal for applications requiring multi-pole switching, such as disconnecting loads or managing power generation.
• Flexible Control Voltage: Operates reliably with a 220 V AC (50 Hz) or 240 V AC (60 Hz) control supply voltage, adapting to common industrial power systems.
• Integrated Auxiliary Contacts: Features 1 NO and 1 NC auxiliary contact, providing essential feedback and control options for complex circuits.
• Robust Screw Terminals: Ensures secure and reliable electrical connections for both main and auxiliary circuits.
• Compact S0 Size: Optimized for space-saving installation in control cabinets and panels.
• Compliance with Global Standards: Manufactured in accordance with IEC 60947-1, IEC 60947-4-1, and IEC 60947-5-1 (for auxiliary switches), guaranteeing safety and performance.
• Expandable Functionality: Supports the addition of further auxiliary switches for enhanced control possibilities.
• Motor Protection Compatibility: Can be combined with Siemens 3RU2 thermal overload relays or 3RB3 electronic overload relays for comprehensive motor protection (for AC-3 applications, specific 3RT23 versions are available).

Functionality & Application

The Siemens 3RT2325-1AP60 contactor is primarily designed for:

• Four-pole switching of weak or non-inductive loads (AC-1): Ideal for resistive loads, heating elements, and other applications where the inrush current is not significantly higher than the operating current.
• Disconnecting loads or power generation plants from the grid: Provides a reliable means of isolating equipment from the power supply.
• Transfer switching: Facilitates the smooth transfer of power between different sources or loads.

Protection and Safety:

• Short-circuit and Overload Protection: All connections (main, auxiliary, and control supply) must be protected using suitable external measures such as circuit breakers or fuses. Refer to the technical product data sheet and configuration manuals for detailed recommendations.
• Overvoltage Protection: The contactor coil can be retrofitted with optional surge suppressors to dampen opening surges and protect the control circuit.
• Contact Reliability: The integrated auxiliary contacts offer high contact reliability, particularly suitable for solid-state circuits with low currents and voltages.

Connection Methods:

• Main Circuit: Features screw terminals for robust and straightforward wiring.
• Auxiliary and Control Circuit: Utilizes reliable screw terminals for easy connection of control wiring.

Maintenance & Expandability:

• Solenoid Coil Replacement: The solenoid coil can be replaced, extending the lifespan of the contactor.
• Auxiliary Switch Expansion: The basic unit can be expanded with additional auxiliary switches to meet diverse application requirements.
