Siemens 3RT2025-2KC80 SIRIUS Power Contactor S0 Frame, 17A, 7.5kW, 34V DC Control Original Brand New

Overview

The Siemens 3RT2025-2KC80 is a high-performance SIRIUS power contactor engineered for reliable switching of motors and electrical loads. Part of the S0 frame size, this compact and robust contactor is ideal for demanding industrial applications. It features a 3-pole design, a rated operational current of 17A (for AC-3e/AC-3), and a power rating of 7.5 kW at 400 V.

The integrated 34 V DC control voltage and a wide control voltage range (0.7-1.25*Uc) ensure versatile and stable operation, especially with PLC outputs. A plugged-in varistor provides surge protection for the coil, enhancing the lifespan and reliability of the device.

Key Benefit

• Optimized for PLC Integration: The 34 V DC control voltage and suitable design make it perfect for direct connection to programmable logic controllers (PLCs), simplifying wiring and control schemes.
• Enhanced Reliability: The built-in varistor protects the coil against voltage spikes, extending the contactor’s service life and reducing maintenance needs.
• Space-Saving Design: Its S0 frame size ensures a compact footprint, allowing for higher density installations in control cabinets.
• Efficient and Secure Connections: Spring-loaded terminals provide fast, vibration-resistant, and maintenance-free connections, improving operational reliability.
• Clear Feedback: The integrated 1 NO + 1 NC auxiliary contacts provide crucial status feedback for monitoring and control systems.

Function and Features

• Power Switching: Efficiently switches a 3-phase motor with a power rating up to 7.5 kW at 400 V.
• Control Circuit: Operates on a 34V DC control voltage with a wide tolerance for voltage fluctuations (0.7-1.25*Uc).
• Auxiliary Contacts: Includes one normally open (NO) and one normally closed (NC) auxiliary contact for feedback and interlocking purposes.
• Surge Protection: Equipped with a plugged-in varistor to protect the control circuit from overvoltage.
• Terminal Type: Features reliable spring-loaded terminals for quick and secure wiring without the need for tools.
• Frame Size: Compact S0 frame size.
• Note: This model does not allow for the addition of an auxiliary switch block.
