This Siemens SIRIUS Surge Suppressor (3RT2916-1EH00) is designed for industrial professionals and engineers who need to protect Size S00 contactors and motor contactors from voltage spikes. Its key benefit is absorbing transient overvoltages to prevent damage to sensitive control circuits, ensuring operational reliability. A potential caveat is its specific DC operation and voltage range (12-250 V DC), requiring careful compatibility checks with the existing system.

Its primary function is to absorb transient overvoltages (voltage spikes) that can occur during the switching of contactors, thereby protecting sensitive electronic components and ensuring the reliability of the control system.
No, this specific surge suppressor (3RT2916-1EH00) is designed for DC operation only and operates within a 12 to 250 V DC range. It is not suitable for AC circuits.
This suppressor is compatible with Siemens SIRIUS contactor relays and motor contactors of Size S00.
It is a pluggable unit that easily clips onto the front of compatible Siemens Size S00 contactors. Ensure the power is off before installation.
The surge suppressor can operate reliably in a wide temperature range from -25°C to +60°C.
This product is specifically a surge suppressor designed to absorb voltage spikes. It does not function as an electromagnetic interference (EMI) filter. Separate components are available for EMI filtering.
The suppressor is designed for DC operation within a control circuit supply range of 12 to 250 V DC.
Verify that the control circuit voltage is within the 12-250 V DC range and that the suppressor is correctly clipped onto a compatible Size S00 contactor. Check for any visible damage.
Ensure the suppressor is properly seated on the contactor. If issues persist, verify the contactor's specifications and the overall system design to rule out other causes of overvoltage.
Confirm that you are using a Siemens Size S00 contactor. This suppressor is not compatible with other sizes or brands.
Setup: The 3RT2916-1EH00 is designed for easy integration. It is a pluggable unit that simply clips onto the front of compatible Siemens Size S00 contactors. Ensure the power to the contactor circuit is switched off before installation. Align the suppressor with the contactor's front interface and push until it clicks securely into place.
Compatibility: This surge suppressor is specifically designed for Siemens SIRIUS contactor relays and motor contactors of Size S00. It operates on DC voltage only, within the range of 12 to 250 V DC. Verify that your existing contactor is a Size S00 model and that your control circuit operates within the specified DC voltage range.
Care: As a passive electronic component, the SIRIUS Surge Suppressor requires minimal care. Keep the unit clean and free from dust and debris. Avoid exposure to excessive moisture or corrosive substances. Regular visual inspection for any signs of damage is recommended. No user-serviceable parts are inside; if damaged, replace the unit.
