Siemens 3RT1966‑1PV3 Main Current Path Surge Suppression Module for Vacuum Contactors 3RT126/7 Original Brand New

Overview

The Siemens 3RT1966‑1PV3 is a high‑quality surge suppression module designed specifically for the main current path. It is engineered for use with Siemens vacuum contactors 3RT126/7 and supports rated operational voltages up to Ue ≤ 690 V AC. It features screw‑mounting installation for secure and reliable integration into your industrial control system. This module belongs to the Siemens SIRIUS line of control and switching components and is categorized under accessories for low‑voltage switching technology.

Key Benefits

• Improved protection: Helps damp switching over‑voltages on the main current path, reducing risk of insulation damage and multiple re‑ignitions of motor windings.

• Seamless compatibility: Tailored for use with Siemens vacuum contactors in the 3RT126/7 range — ensuring optimal fit and performance.

• Industrial durability: Designed for demanding industrial environments with screw‑mount secure installation and trusted Siemens build quality.

• Compact and efficient: Lightweight and compact dimensions (approx. 95 × 112 × 63 mm) make integration into control panels straightforward.

• Original Siemens specification: Manufacturer part number 3RT1966‑1PV3, EAN 4011209512252, ensures genuine component with full documentation.

Function & Features

• Surge suppression: Attenuates voltage spikes and protects the main current path when switching off three‑phase motors connected to vacuum contactors.

• Rated operational voltage: Supports Ue ≤ 690 V AC (and for reference the variant 3RT1966‑1PV4 supports up to 1000 V AC) so you know it’s specified for high‑performance applications.

• Mounting style: Screw mounting for reliable, fixed installation on control panels or switchgear, enabling stable mechanical and electrical connections.

• Installation compatibility: Suitable for feeder side connection of vacuum contactors (terminals 2‑T1 / 4‑T2 / 6‑T3) as per Siemens SIRIUS recommendations.

Application

• Industrial motor control systems using Siemens vacuum contactors 3RT126/7

• Automation panels requiring suppression of switching surges and enhanced motor protection

• Control cabinets where high‑voltage (up to 690 V AC) switching demands robust suppression modules

• Retrofitting or upgrading existing vacuum contactor installations to improve longevity and reliability
