Siemens 3RT1926-1BD00 Suppressor Module

Product Description

The SIEMENS 3RT1926-1BD00 is a suppressor module designed to reduce voltage spikes and electromagnetic interference generated when contactors and relays switch on and off. This type of surge suppression accessory mounts directly to compatible SIEMENS contactor frames, protecting sensitive control circuits and extending the service life of switching devices. It is a compact, low-profile component that electricians and industrial control technicians install during panel builds, motor control center work, and automation system service. At 0.029 pounds and measuring approximately 2.087 inches by 1.654 inches by 0.472 inches, the module fits tight enclosures without significant space impact.

This suppressor module is suited for use in commercial and industrial electrical systems where contactor-driven loads such as motors, transformers, and solenoid valves create inductive switching transients. It is typically installed in motor control centers, machine control panels, and building automation panels. The module is used by licensed electricians and industrial automation technicians during new installations or as a replacement in existing contactor assemblies to maintain clean control-circuit operation.

Key Features

• Suppresses inductive voltage spikes at the contactor coil to protect downstream control components
• Direct-mount accessory design for compatible SIEMENS contactor frames
• Compact form factor at 2.087 inches x 1.654 inches x 0.472 inches fits space-constrained enclosures
• Lightweight at 0.029 pounds — minimal load contribution to panel assemblies
• Sold as 1 unit per pack

Compatibility

Designed as an OEM-style accessory suppressor module for compatible SIEMENS contactor assemblies. Consult SIEMENS documentation to confirm frame size and coil voltage compatibility before ordering.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the control panel before installing or replacing the suppressor module. The module snaps or mounts directly onto the contactor body — do not force or modify the mounting clips. Verify coil voltage compatibility between the suppressor module and the contactor before energizing the circuit.
