The Siemens 3RT2916-1CD00 is a genuine Siemens SIRIUS RC Element Surge Suppressor designed for compatible 3RT2.1 contactors and 3RH2 auxiliary contactors. This contactor coil surge suppressor is designed to reduce switching-related voltage transients generated by inductive contactor coils, helping protect connected control components and support reliable operation of industrial automation and motor control systems.
The 3RT2916-1CD00 RC suppressor supports a wide control supply range of 127–240V AC at 50/60Hz and 150–250V DC. The RC element provides effective suppression of switching interference in AC and DC contactor control circuits, making it suitable for industrial control panels, motor starters, PLC-based automation systems, machine control cabinets and OEM electrical equipment.
Designed for S00-size Siemens contactors, the 3RT2916-1CD00 can be plugged onto the front of compatible 3RT2.1 contactors and 3RH2 contactor relays. Its clip-on mounting and compact construction make installation convenient while helping maintain a space-efficient control-panel layout. The specified dimensions are 46 mm × 28 mm × 9 mm.
The Siemens SIRIUS RC element surge suppressor operates in an ambient temperature range of -25°C to +60°C and has a storage temperature range of -40°C to +80°C. The official Siemens catalog lists the product as an active PM300 product, with a net weight of approximately 0.007 kg.
The Siemens 3RT2916-1CD00 is an ideal accessory for motor control panels, DOL starters, MCC panels, industrial automation systems, PLC control panels, machine builders, OEM control cabinets and electrical switching applications where compatible Siemens SIRIUS contactors are installed.
