Siemens 3RT1935-5AK61 Ac Suppressor Module

Product Description

The SIEMENS 3RT1935-5AK61 is an AC suppressor module designed to reduce voltage spikes and electromagnetic interference generated when contactor coils de-energize. Suppressor modules of this type are wired directly across the control coil terminals, clamping transient voltages that would otherwise damage sensitive control circuitry or cause nuisance trips in PLC and relay logic. This module is a direct accessory for compatible Siemens 3RT contactor frames and is installed by licensed electricians or qualified industrial maintenance technicians.

This suppressor module is used in industrial and commercial motor control applications where 3RT-series contactors are deployed. Typical installations include motor control centers, machine control panels, and HVAC equipment panels where AC control voltage coils require transient suppression. The compact form factor allows mounting directly on the contactor body without additional hardware or panel space.

Key Features

• Suppresses inductive voltage transients on AC contactor coils to protect downstream control components
• Mounts directly onto compatible 3RT contactor frames for tool-free accessory installation
• Compact footprint measures 2.640 x 1.700 x 4.650 inches for space-constrained panel installations
• Lightweight construction at 0.150 pounds adds negligible load to the contactor assembly

Compatibility

Designed as an OEM-style accessory suppressor module for Siemens 3RT-series contactors. Verify frame size and coil voltage compatibility against the contactor model before ordering.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the NEC and applicable local codes. De-energize and lockout/tagout the panel before installing or removing any suppressor module. The module connects across the contactor coil terminals — confirm the control circuit voltage matches the suppressor rating before energizing. Do not install with power applied.
