Siemens 3RT1975-5XF42 Changeover Operating Mechanism 110V DC for 3RT1 Contactors S6-S12, 24-110V DC, Spring-Loaded Terminal Original Brand New

Overview

The Siemens 3RT1975-5XF42 is a critical spare part and accessory, specifically a changeover operating mechanism (often referred to as a coil or withdrawable coil) designed for the larger power contactors in the SIRIUS 3RT1 family. This mechanism is engineered for reliable operation in demanding industrial applications, offering exceptional control and integration capabilities.

It is tailored for use with the high-current contactors:

• 3RT107.-.X..-0LA2 (3-pole power contactors)
• 3RT147.-.X..-0LA2 (4-pole resistive load contactors)

Key Features and Function

• Product Type: Changeover Operating Mechanism / Withdrawable Coil.
• Contactor Compatibility: Exclusively for Siemens SIRIUS 3RT1 contactors, sizes S6, S10, or S12 (indicated by the '7' in the contactor number).
• Supply Voltage: 110 V DC with a wide operating factor range of x (0.7-1.25) to ensure reliable switching under varying voltage conditions.
• PLC Integration: Features a dedicated PLC input for control signals ranging from 24 V DC to 110 V DC, simplifying integration into modern Programmable Logic Controller (PLC) systems.
• Connection Technology: Equipped with secure and fast spring-loaded terminals (also known as spring-type terminals), which provide vibration-proof and maintenance-free electrical connections.

Benefit

1. Guaranteed Compatibility & Performance: As an original Siemens spare part, it ensures perfect fit and long-term reliable performance with the SIRIUS 3RT1 contactor series.
2. Optimized Control: The wide 110 V DC supply voltage range and PLC input feature minimize control system complexity and enhance switching stability.
3. Robust Connection: Spring-loaded terminals offer superior contact reliability compared to screw terminals, making them ideal for environments subject to vibration or frequent maintenance checks.
4. Reduced Downtime: Quick and easy replacement allows for minimal disruption to essential industrial processes.
