The Siemens 3RT2916-1LM00 is a genuine Siemens SIRIUS Surge Suppressor with Suppression Diode and LED, designed for compatible Siemens 3RT2.1 contactors and 3RH2 auxiliary contactors. This contactor coil surge suppressor helps suppress voltage transients generated when a DC contactor coil is switched, reducing electrical stress on the control circuit and supporting reliable operation of connected automation components. Siemens specifies this accessory for S00-size contactors.
The 3RT2916-1LM00 suppression diode with LED is designed for a 24–70V DC control supply voltage. The integrated LED provides a visual indication of the control circuit status, while the diode suppression arrangement helps protect the contactor control circuit against switching-related voltage transients. This makes the accessory suitable for industrial motor control, automation panels, PLC control systems, machine control panels, OEM equipment and electrical control cabinets.
Designed for convenient installation, the Siemens SIRIUS 3RT2916-1LM00 uses clip-on mounting and can be installed in any mounting position on compatible contactors. Its compact dimensions of 46 mm height × 28 mm width × 9 mm depth make it suitable for space-efficient installation in industrial control panels. The specified operating ambient temperature is -25°C to +60°C, with a storage temperature range of -40°C to +80°C.
The Siemens 3RT2916-1LM00 surge suppressor is suitable for motor starter assemblies, Motor Control Centers (MCC), DOL motor starters, industrial automation panels, PLC-controlled machinery, OEM control cabinets, factory automation systems, electrical control panels and industrial switching applications using compatible Siemens 3RT2.1 and 3RH2 contactors.

Genuine Siemens SIRIUS accessory
The Siemens 3RT2916-1LM00 is a suppression diode with LED surge suppressor used with compatible Siemens 3RT2.1 contactors and 3RH2 auxiliary contactors to suppress voltage transients associated with DC contactor coil switching.
The 3RT2916-1LM00 is designed for a 24–70V DC control supply voltage.
This surge suppressor is specified for Siemens 3RT2.1 contactors and 3RH2 auxiliary contactors.
The 3RT2916-1LM00 uses a suppression diode with LED for DC contactor coil suppression.
Yes. The product designation specifies an interference suppression diode with LED, providing visual indication for the control circuit.
No. This particular model is specified for 24–70V DC control supply. For AC control applications, the appropriate Siemens surge suppressor variant should be selected according to the contactor coil voltage.
The surge suppressor uses clip-on mounting and can be installed in any mounting position on compatible contactors.
The specified dimensions are 46 mm height × 28 mm width × 9 mm depth.
The specified operating ambient temperature range is -25°C to +60°C, while the storage temperature range is -40°C to +80°C.
No. The 3RT2916-1LM00 is a surge suppressor accessory with suppression diode and LED, not a complete contactor. It is designed for use with compatible Siemens 3RT2.1 and 3RH2 contactors.
