3RT2916-1BB00

The 3RT2916-1BB00 is a surge suppressor module from Siemens' SIRIUS 3RT2/3RH2 series, engineered to protect sensitive electronic control devices, PLCs, and solid-state outputs from destructive voltage spikes caused by contactor coil de-energization. Designed to clip directly onto the coil terminals of Size S00 contactors and control relays, this protective accessory suppresses inductive voltage transients across control circuits operating at . Electrically, the 3RT2916-1BB00 utilizes a varistor (MOV) network matched to control circuit requirements operating with a control supply. By clamping overvoltage transient spikes generated when the contactor coil drops out, it prevents electromagnetic interference on nearby control lines and protects sensitive semiconductor outputs from voltage breakdown, maintaining stable operation in automated control systems. Mechanically, the 3RT2916-1BB00 is housed in a compact, flame-retardant module that clips toollessly into designated mounting slots on the front or top of Size S00 contactors. Equipped with touch-safe IP20 screw terminals, it integrates seamlessly into the contactor footprint without occupying extra DIN-rail space or obstructing primary power wiring inside control enclosures.
