Siemens 3RT2625-1AP65 Capacitor Contactor 16.7 kVAr, 220V/240V AC, Size S0 Original Brand New

Overview

The Siemens 3RT2625-1AP65 is a high-performance capacitor contactor from the SIRIUS series, specifically designed for switching capacitive loads (AC-6b) in reactive power compensation systems. This specialized contactor effectively manages the high inrush currents associated with switching capacitors, ensuring the stability and longevity of your power supply network. Featuring integrated precharging resistors, the 3RT2625-1AP65 limits peak charging currents, minimizing stress on the electrical system. Built to the highest standards, including IEC 60947 and IEC 61921, this contactor offers a reliable and safe solution for a wide range of industrial applications.

Key Benefit

• Extended Equipment Lifespan: By effectively limiting inrush currents, the 3RT2625-1AP65 protects connected capacitors and other system components from stress, extending their operational life.
• Improved Power Quality: Minimizing current peaks reduces negative impacts on the power supply network, leading to better overall power quality and system stability.
• Enhanced Reliability: Robust design and adherence to international standards ensure dependable operation in demanding industrial environments.
• Versatile Application: Suitable for switching both choked and unchoked capacitors in reactive current compensation systems, as well as for switching converters.

Features & Function

• Capacitor Contactor (AC-6b): Specifically engineered for capacitive loads, rated at 16.7 kVAr at 400 V.
• Integrated Precharging Resistors: Leading auxiliary contacts engage precharging resistors before the main contacts close, effectively limiting peak charging currents.
• Control Supply Voltage: Operates on a dual-frequency coil: 220 V AC, 50 Hz and 240 V AC, 60 Hz.
• Auxiliary Contacts: Equipped with a 1 NO (Normally Open) + 2 NC (Normally Closed) configuration for flexible control and signaling.
• Connection Type: Secure screw terminals for reliable and straightforward wiring.
• Compact Design: Size S0 form factor allows for space-saving installation in control panels.
• Compliance: Meets stringent international standards including IEC 60947-1, IEC 60947-4-1, IEC 60947-5-1, IEC 60831-1, and IEC 61921.

Protection and Safety

The Siemens 3RT2625-1AP65 requires appropriate short-circuit and overload protection for all connections (main, auxiliary, and control). For detailed information, refer to the technical product data sheet and configuration manuals. Optional surge suppressors (RC elements, varistors, etc.) can be retrofitted to protect the control supply voltage connection from overvoltage, though this may slightly increase the contactor’s break times.

Expansion Possibilities

The 3RT2625-1AP65, being a 3RT262 series contactor, comes with an integrated auxiliary switch setup. It can be further expanded with additional lateral auxiliary switches for more complex control schemes, ensuring flexibility for your specific application needs.
