Siemens 3RT1935-5AP61 Ac Suppressor Module

Product Description

The SIEMENS 3RT1935-5AP61 is an AC suppressor module designed to reduce voltage transients and electrical noise generated when contactor or relay coils de-energize. Suppressor modules like this one protect sensitive control circuitry by clamping inductive kickback at the coil terminals. The unit mounts directly to compatible SIEMENS 3RT and 3RH series contactors and relays, making it a standard accessory for motor control center builds, panel assemblies, and industrial control panels. Installation is handled by electricians and controls technicians working on low-voltage motor control and automation systems.

This suppressor module is suited for AC coil circuits and is used in both commercial and light industrial applications where contactor noise suppression is required. It is a direct-mount accessory intended for panel-level installations in motor starters, reversing starters, and relay logic assemblies. The compact form factor keeps wiring clean and minimizes space usage inside enclosures.

Key Features

• Suppresses inductive voltage transients on AC contactor and relay coils
• Direct-mount design for tool-free attachment to compatible SIEMENS contactors
• Compact footprint at 2.638 inches x 1.693 inches x 4.646 inches
• Lightweight at 0.254 pounds, adding minimal mass to the assembly
• Protects downstream control circuitry from coil-generated electrical noise

Compatibility

Designed as an OEM-style suppressor accessory for AC coil contactors and relays in the SIEMENS 3RT and 3RH series product families, as indicated by the part number series designation.

Installation Notes

Installation is performed by a licensed electrician or qualified controls technician. De-energize and lock out the control panel before attaching or removing any suppressor module. Verify that the coil voltage rating of the suppressor matches the AC control voltage in the circuit before installation. Follow applicable NEC requirements for industrial control panel wiring and component mounting.
