Siemens 3RT2617-1AF05 Capacitor Contactor 12.5 kVAr, 110V AC Coil, 2 NC Aux Contacts Original Brand New

Overview

The Siemens 3RT2617-1AF05 is a specialized 3-pole capacitor contactor designed for switching capacitive loads in reactive current compensation systems. Featuring an AC-6b rating of 12.5 kVAr at 400V, this S00 size contactor is equipped with an integrated precharging resistor circuit. This unique design limits the inrush current during switching, minimizing negative impacts on the power supply network. The device is powered by a 110V AC, 50/60 Hz control supply voltage and includes 2 normally closed (NC) auxiliary contacts with screw terminals for reliable connections.

Features & Functions

• Capacitor Switching: Specifically engineered for AC-6b applications, the 3RT2617-1AF05 efficiently switches choked or unchoked capacitors up to 12.5 kVAr.
• Integrated Precharging Resistors: Leading auxiliary contacts close before the main contacts, introducing precharging resistors that limit the high peak charging current of capacitive loads. This reduces network disturbances and enhances system stability.
• Robust Design: Built to IEC standards (IEC 60947-1, IEC 60947-4-1, etc.), ensuring reliable and safe operation.
• Flexible Control: Operates with a 110V AC, 50/60 Hz coil, making it compatible with a wide range of control circuits.
• Auxiliary Contacts: Comes with two freely accessible normally closed (NC) auxiliary contacts, providing additional functionality for signaling or interlocking within your control system.
• Easy Connections: Equipped with secure screw terminals for both main and auxiliary circuits.

Benefit

• Improved Power Quality: By limiting inrush current, this contactor prevents voltage sags and harmonics, improving the overall quality of your power supply network.
• Extended Equipment Life: Reduces stress on both the capacitor bank and the contactor itself, leading to a longer operational lifespan for your equipment.
• Space-Saving Design: Its compact S00 size allows for efficient use of space within control panels and electrical cabinets.
• Enhanced Safety: Complies with multiple international standards, providing assurance of a safe and dependable product.
• Easy Integration: The standard 110V AC coil and screw terminals simplify installation and integration into new or existing systems.
