Siemens SIRIUS 3RT2936-1JJ00 Varistor Surge Suppressor with LED, 24-48V AC / 12-24V DC, for 3RT2 Contactors Original Brand New

Overview

The Siemens SIRIUS 3RT2936-1JJ00 is a highly efficient, clip-on surge suppressor module designed specifically for the SIRIUS 3RT2 series of power contactors (Sizes S2 and S3). Utilizing varistor technology and an integrated LED indicator, this compact accessory effectively dampens opening surges in the contactor’s coil, protecting the control circuit from damaging voltage spikes. Its wide operating voltage range makes it versatile for both AC (24-48V) and DC (12-24V) control circuits.

Key Benefit

• Enhanced Equipment Protection: Prevents damaging voltage spikes, significantly extending the service life of your contactor and other sensitive control components.
• Instant Diagnostic Feedback: Integrated LED provides immediate visual confirmation of the control supply voltage status, simplifying troubleshooting and reducing downtime.
• Easy Installation: Features a clip-on design that mounts directly into the contactor’s available slot without increasing the contactor’s overall external dimensions, ensuring a quick and clean setup.
• Versatile Application: Suitable for a wide control voltage range: 24-48 V AC (50/60 Hz) and 12-24 V DC.

Functionality

The varistor-based design absorbs and limits voltage surges caused by inductive loads during switching operations. The integrated LED indicates the suppressor’s active status, allowing for easy diagnostics and monitoring. Designed to integrate seamlessly with Siemens contactors, it maintains optimal electrical performance in demanding industrial environments.
