Siemens 3RT29161JJ00 Surge Suppressor Size S00

Product Description

The SIEMENS 3RT29161JJ00 is a surge suppressor accessory designed for use with Size S00 contactors. It protects control circuits and coil windings from voltage transients and inductive kickback that occur when a contactor de-energizes. By clamping surge energy at the source, it reduces interference with adjacent low-voltage control components and extends coil service life. Licensed electricians and industrial controls technicians are the primary installers. This part is a direct snap-on or plug-in accessory, sized specifically for the S00 contactor frame.

This surge suppressor is suited for use in motor control centers, panel boards, and control cabinets where Size S00 SIEMENS contactors are installed. Typical applications include small motor starters, lighting contactors, and HVAC equipment control circuits in both commercial and light industrial settings. Its compact form factor allows installation in tight enclosures without modification to the existing wiring layout.

Key Features

• Designed for Size S00 contactor frames for direct accessory mounting
• Suppresses inductive voltage transients to protect coils and adjacent control components
• Compact dimensions of 2.205 inches x 1.220 inches x 0.394 inches allow use in confined panel spaces
• Lightweight at 0.015 pounds, adding negligible mass to the contactor assembly
• Packaged individually, one unit per pack

Compatibility

Designed as an OEM-style surge suppressor accessory for SIEMENS Size S00 frame contactors. No additional compatible model numbers were specified in the available product data.

Installation Notes

Installation should be performed by a qualified electrician with the control panel de-energized and locked out per NFPA 70E lockout/tagout procedures. The suppressor mounts directly to the contactor coil terminals without additional tools in most configurations. Verify that the suppressor voltage rating matches the coil control voltage before energizing. Consult the contactor manufacturer documentation for accessory mounting orientation requirements.
