Varistor-based surge suppression Protects coils and electronics Clip-on mounting for easy installation Wide AC/DC control voltage range Compact design Enhances system reliability

Product description

The Siemens 3RT2916-1BB0 is a varistor surge suppressor module designed to protect control circuits, contactors, and relays from voltage spikes and transients. It is compatible with Siemens SIRIUS 3RT2.1 contactors and 3RH2 auxiliary contactors. This module features clip-on mounting for easy installation on a DIN rail and is rated for 24-48V AC (50/60 Hz) and 24-70V DC control supply voltages.

This surge suppressor is crucial for enhancing the reliability and lifespan of sensitive electronic components in automation systems. By clamping transient voltages, it prevents damage to coils and electronics, reducing downtime and maintenance costs. Its compact design ensures it does not add significant bulk to control panels.

Stanlo Automation, a veteran-owned surplus industrial parts distributor, offers the Siemens 3RT2916-1BB0 surge suppressor. We provide quality components to ensure the longevity and performance of your automation systems.
